Be Kind Rewind Trailer

I don't know what to make of this trailer for Be Kind Rewind.  When all the tapes in their video store are accidentally erased, they go and recreate all the films themselves... thus hilarity and antics ensue. 

It looks like it should be completely awful, as if this should be a film starring Jon Heder and David Spade.  Instead, it stars Jack Black and Mos Def, and is directed by Eternal Sunshine of the Spotless Mind's Michel Gondry.  I feel like I have to trust them, don't I?
