I notice that not too many fans are especially fond of the intro used for the final three years. Some have said that the pictures and names move much too fast and they don't like how all the frames are different colors.
I have a different take on it. I've always read that the producers designed the new opening, starting in the twelfth season, to make the intro "safe" for the 1990s. Now, I've always been a little uncertain exactly what was meant by "safe", but I must say that I'm on-board with their decision to turn things back to mimic the classic theme from the show's heyday.
While I can agree that the pictures and names do move a little fast, I must say that I personally liked how the picture frames were all in different colors. I understand that some might find them a little amateurish, but I think it gives those openings a little homey feeling. Not only does it keep the openings from looking too bland, some people occasionally have different colored picture frames hanging on their living room wall. It just makes the openings look like a stroll down memory lane all the while why pictures are hanging on a memory wall, or our TV screens in this case.
