If you want to make a damned movie, get in the movie business! If you want to make GAMES then make them FUN!
There's nothing inherently wrong with cinematic games, though. Compare a snore-fest like LA Noire to the Mass Effect series.

LA Noire was a barely-interactive 20 hour movie which ground onward inevitably with or without you.
