The funny thing about this one is critical reaction was favorable. The film actually holds a 68% critic rating on Rotten Tomatoes, but only 50% audience. Critic consensus was summed up as that "Snakes on a Plane lives up to its title, featuring snakes on a plane. It isn't perfect, but then again, it doesn't need to be."
Permanent Placeholder: The movie was going to be renamed Pacific Air Flight 121 for its release, but then its B-movie working title attracted a flurry of attention on the internet, and Samuel L. Jackson insisted that he'd only signed on to the film because of its Exactly What It Says on the Tin title. The producers kept the working title to cash in on the online hype.
Vindicated by Cable: It's not the kind of movie you should watch in a quiet theater. It's the type of movie you should watch at home with friends as you laugh and snark the hell out of it. The campiness of some of the TV edits also helps boost the snark factor for some.
