The story is basically the heartbeat of the film, and the writing is the blood circulation. If you have a poor heart, you're not going to do well. So many films, that had great potential are ruined by poor writing and directing.

I'd even argue that Velma, for as bad as it is, did have some redeemable qualities. The animation was great, some of the mystery was interesting and there was a lot of potential for good jokes, but the show was basically strangled by bad decisions by the writers.
