Is Realism Ruining Films?

[Foggy]

There are things you stretch your imagination to get the full enjoyment, like sci-fi and what not, that's when stretching imagination is fun. But then there are plot holes and stupid characters that cannot be ignored, that's when it's not fun and becomes insulting, films can be fun and ridiculous, but as long as the characters and story are grounded in a sense of reality that truly makes a film buy-able.

For example, you mention Alien, if in that film, they decided that they could grow wings and fly out into space escaping the ship and destroying the alien because it was the only conceivable way for the writers to come up with a way to get a happy ending, then I would be pissed, because that's a cheap ending that isn't grounded in a reality, the idea of the film is that they are stuck in space, no one can hear them or save them, and they can't just run out, that's the film's reality.
