People always rationalize a bad movie by saying "it is what it is", it's a "popcorn flick" or it was just a "fun" experience ect. How annoying is that?
I don't consider it a rationalization, I think if you look at films, there are a lot of goals people have with films they make.
Frankly, I consider a large number of the oscar films to be far less entertaining than a lot of movies, but they are really good within the context of the aim the filmmakers had with the film, they are a great success.
Michael Bay doesn't set out to make films that engross you in character development and feature intricately woven plots, his goal is to make a 2 hour film that gives the viewers an exhilarating and fun experience, and to me, that's where the term popcorn flick comes from, movies that are more to be like a visual "ride" than a film to be measured for the subtle qualities.
I think it's stupid to try and hold every film to the same standards, the beauty of movies is there's a wide range of types and styles and things to gain from the watching.
I watch Transformers to give my mind some fun time, I watch Batman Begins to get engrossed in characters, I watch City of Angels to watch an interesting story.
I can discuss films and find pros and cons in them, but some of the opinions I read at this site, it seems almost like people have forgotten how to just have fun watching it, like there's this epic measure all films have to live up to and anything short is just trash. There are some really bad movies, and then there are some that may seem bad by high standards, but for certain functions they are perfect.
