It seems In Sickness & In Health is a series that continually evolved, frequently from necessity.
Wikipedia says that Johnny Speight was warned about racist language in 1988, the outcome being that it was agreed Alf's epithets would be discontinued and the character of Winston would be written out. I wonder, though, if this was actually the outcome of an evolution rather than a revolution. Series Three aired in 1987 and even here Alf's language is noticeably tamer and less colourful. The few epithets we've had have seemed somehow to have less malice behind them (more often than not they've been during banter with someone acquainted with Alf who simply laughs or rolls their eyes or takes no notice at all).
Of course, this leaves the question of how much the show can change before it becomes unrecognisable. Would it have been better to have simply accepted that Alf was a dinosaur who wasn't going to stop raging and end the series there and then rather than changing him which, in turn, risks undermining the very concept of the series? In theory I would have said it would. Alf is a character who allowed Johnny Speight to shine a light on some of the ugly recesses of British culture of the day. Censoring him would seem to remove the main outlet for satire.
In practice, though, the change hasn't been too harmful: so far, at least. I haven't missed the language. As mentioned, it was never comfortable to watch - especially used as liberally as it was in many series of Till Death Us Do Part. By now we know what Alf is about, so making that more implicit is fine with me. There is also the fact that Alf might just genuinely have evolved his views. More than two decades have passed since we first met him, and he has life experiences - from becoming a grandparent to several house moves to becoming a senior citizen, a carer and eventually a widower - that will have no doubt facilitated change.
At this point in the series, he now shares his home with a man who is both black and gay. Someone who would have been treated by Alf of old with forceful antipathy is now the subject of the kind of same good natured teasing he lavished on his own wife. Winston may challenge him in some ways and embarrass him in others, but Alf - in his own way - seems genuinely appreciative and even quietly fond of him. If we'd jumped from 1965 Alf to this point it would have seemed out of character, but we've seen him evolve over a long time.
The series itself may continue to become an ever more conventional sitcom. But it's a good conventional sitcom. Warren Mitchell's Alf was always the centrepiece, and this series is proof that the character is versatile enough to thrive no matter what changes around him.
Evolution brings endings, though. The Series Two Christmas special marked Una Stubbs's final appearance as Rita. Come Series Three she's been written out in a way that feels unsatisfying and unfinished. Having her in Liverpool made sense because she could not appear and it would raise no questions. Now, though, she's divorced from Mike and appears to be somewhere in the vicinity hiding out of sight.
We actually see "Rita" at the beginning of Series Three... or at least we see her legs as she carries on with the doctor in his surgery. Later we learn she and the doctor are engaged. It's a peculiar situation. The doctor appeared after Una had left the series so we've never seen them together, and the whole engagement arc and Alf's resentment towards the doctor for his conduct is done with solely the doctor present. And yes - I keep saying "the doctor" because I don't think he's even been given a name! There's even an episode where Rita and the doctor arrange for a telephone to be installed at Alf's home, but there's no sign of Rita. It feels very badly written, and feels very much like the episodes were written with Una in mind but they couldn't get her.
In other "lazy writing" tropes for long-running sitcoms, there's still much repeated material. Alf's visit to the DHSS felt familiar but was done so well I could forgive it. The most notable reprise was Alf getting stuck in the first floor window, previously seen in one of the final episodes of Till Death Us Do Part. Perhaps it was felt that some twelve years on it was excusable, but watching them so closely together, it felt a bit "here we go again", and - despite better production values - it didn't feel as technically impressive as the earlier version. There are a couple of things that might excuse the choice to reprise this. Firstly, it may have already been understood that Till Death Us Do Part would not be repeated much. The series hadn't been "cancelled" in the 21st Century manner, but - judging by the conversations taking place around language - was perhaps viewed as less palatable even then. That's as good a reason as any to commit this to film again. The other reason is that the involvement of the lorry in the reprise version seems to come from another episode of Till Death Us Do Part which is now lost to the mists of time having been wiped (only an off-air audio recording exists). This is an even better reason to do it all again.
Looking at the cast list for the series, it seems there are wholesale changes in store for Series Four. Supporting players such as Mrs Johnson and Mr Kittel will no longer be seen.
Even more crucially, the Christmas special I just watched was Winston's last episode, which seems a real shame since the dynamics were working perfectly. I assume Eamonn Walker left to do The Bill, but am unclear of the circumstances. Wikipedia suggests that Winston was purposely written out as part of the drive to tone down Alf's racist language (which would presumably also apply to Mr Kittel), but there are two gaping holes in this idea. Firstly, it seems both ironic and incredibly wrong that non-white actors should lose their jobs in a drive by the series to be less racist. Secondly, it appears that Winston will be replaced by another black character who serves much the same function. This leaves me to feel that Eamonn left the series by choice and this was written around rather than the writing requiring his exit.
I'll know more once I begin watching Series Four, but I can't help feeling this could be a turning point for the series... and not in a good way.
