For me, I'd go with Borderlands 2. Can't go wrong with an epic train heist to start off a game.
I was gonna say Sonic Unleashed tooI haven't played too many games, but the Sonic Unleashed intro is really sick, and probably has to be my favorite
The cutscene when you start playing a new character in Skyrim is probably my favorite.
