HAHA...that 2CV commercial was great. I was just about to ask, why bother making a transformer from a 2cv, then when it fell apart at the end, it was just great 




I didn't know Megatron was in it, but I guess you could easily explain Galvatron returning to his Megatron guise somehow.
IMO the movie should begin with the war on Cybertron, followed by the the Transformers spending millions of years "sleeping" beneath the earth and then being awakened by an earth quake.
