Since a lot of us are driven crazy by horrible science in the movies, I wonder what is the general tolerance level that people here have for bad science? If the actors in a movie make a glaring error does it ruin the movie for you? Does it usually take more than one, or can you forgive all if you're having fun? Does it vary from movie to movie? One set of standards for a Star Trek, another for a movie about a contemporay trip to Venus?
For me, personally, it depends on the quality overall of the movie I'm watching. I'm able to fogive some pretty large holes in a movie like "Signs" because I found it to be an effective thriller, where I'm unable to forgive holes in a movie like "Mission to Mars" because it felt like sitting in a dental chair while watching it.
