Whoa, wait. While we're all off-track and such, I'd like to interject that I'm not the biggest fan of whedon, never got Buffy or Angel, and couldn't STAND his original screenplay for Alien Resurrection, much less his revised and then hacked up later drafts--I do recognize his hand in Toy Story, and in Speed, and the 13 episodes of Firefly were great television, and the movie CERTAINLY wasn't mediocre.
Did anyone watch it? No. But the movie was pretty critically lauded overall. Reviewers tended to like it. Certainly wasn't MEDIOCRE, as far as the general consensus went. And post viewing polls done showed audiences really ENJOYED the movie--if they got into the theater. Most of em didn't, because the marketing was ass on a biscuit. Horrible marketing. Sorta the same thing with the series Firefly. No one knew how to sell it, so they didn't. And it was DOA. Same with the movie.
But it wasn't mediocre. The movie, that is. Or the show. But I can't deny it didn't make bank at the theater, not by a longshot.
