I have a friend who thinks every movie he's ever seen is awesome. I learned a few years back not to take his advice on movies. I wish I could enjoy everything as much as he does though. I guess it probably helps that he's always drunk and stoned, and I'm neither.
I'm that friend minus the drugs. I would say 9/10 times I like the movie. I just enjoy experiencing other people's creativity. I do try to mention my bias when people ask me if they should watch something.
I enjoy almost everything I see in the theater. There have been a fair few movies that I enjoyed on the big screen but on rewatching at home was like "Why did I like this shit?"
I find that I don’t go to the theater as much as I used to so I end up saving it for movies that I think will be better there.
I can over do it though and be burned by my expectations. I was very disappointed in the Avatar sequel because I felt the movie might have looked better at home where I can turn off stupid things like changing refresh rate.
to be fair, if someone watches the whole movie, then it's probably because it's a good movie. otherwise, that person would've stopped watching once they realised that they didn't like what they were watching.
