I'm all for alternate universes, but I just can't see this movie being the prequel to the Bayverse. The overall tone and style are completely different.
If TF-1 is the first chapter of an entire new series of movies set in their own closed universe, I'll be all for it. Also, let the art style be consistent and stay 100% animated through the series, please.
This way, having Bee be the same age as Optimus and Megatron would stop bothering me at the very least. I mean, in most universes, Bee is supposed to be a "teen", Optimus a "30-something adult", and Megatron be "in advanced middle age".
In this new series, having those 3 be the same age will surely bring some new dynamics and characters interactions.
Regardless, I'm looking forward this movie.
