how much are you willing to suspend disbelief for a tv show or movie?

I don't mind when movies require imagination. However, certain movies drive me insane (See: 10,000 BC/almost any disaster movie) with their blatant inaccuracies.

It depends on how good the rest of the show is. I would be annoyed, but would stay interested if it was good enough. If the writing just turned into a big contradictory mess, I would obviously stop.

I'm willing to suspend disbelief. I mean, I know going in it's not a documentary. The people are all just pretending to do something on a pretend set... so I don't expect it all to make sense. I will make fun of certain ridiculous aspects of it but it certainly won't keep me from watching it or enjoying it.

I am willing to suspend disbelief if something is pulled off well. If there is good world building, or lore behind things it can suck you into it, so long as the characters are well done. Occasionally I will have issues with it, but give it a shot to see if it works out. A good example that bothered me was in Buffy the Vampire Slayer when she suddenly has a sister, but it isn't really explained why and none of the characters notice anything is out of the ordinary. I had a hard time with that one, but the story eventually worked itself out.

The most amazing thing about fiction movies is that you do not expect what you will see, and that gives you enthusiasm to watch. It is like a surprise you don't expect and makes you happy after open it.

I can suspend disbelief easily and enjoy doing so, but sometimes I get distracted by bad writing or production. A couple distractions are ok, but when they build up I get pulled out. If the writing/premise are creative and interesting and funny I can forgive a lot. If the writing is bland, and the "rules" of the 'verse are contradicted, and the set/costume design make no sense, and characters are suddenly OOC, and the genre is compromised to pander to the mainstream, eventually I get fed up and have trouble using my imagination to keep myself engaged.

I can fairly easily suspend disbelief up until something starts to contradict itself. Once things start to get crazy over the top or start contradicting previously established rules, I start to get a little cranky.

I'll echo Sam and T&A, if the writers established something, DON'T CHANGE IT.

Of the shows I've seen, I think Red Dwarf was the worst one for this. 80's cartoons did this too. Thundercats, He-man, GI Joe, etc were all bad with things.

I really hated that part in the Harry Potter movie when they dove under the lake to for sword and neither were cold >: ( there was SNOW

It depends on a lot of factors, internal consistence, whether or not it well written if there is a good pay off. etc.
