My friend and I were talking about this the other day. I was talking about how I always thought the TFTM had a series finale feel to is, what with the war being over and the Autobots winning. Also not to mention that a good chunk of the characters we knew were killed off. So, what if instead of season 3 taking place after the movie, it went back to "present day" (1986) and filled in part of the 19 year gap? I personally think that any emotional attachment to the characters would weaken, since we would already know what was going to happen. It's one of the reasons that I didn't like the Star Wars prequels. It's really hard to care for characters that you know won't live.
