You know, I'm really considering seeing the new Transformers movie. Why? Well, it'll be fun. I don't think I'm going to hate it. At the very least, I can appreciate the modeling and rendering techniques that went into it, but moreover, like I said, it'll be fun. I don't know what these movies entail, as I've only seen the first, and it's been so long that all I remember are some action scenes, slapstick humor, and a 'chosen one' adventure with a main protagonist that I didn't really like. Really, I don't care.
The movie isn't designed to give you something to think about afterwards. It's basically like visual cocaine. From what I've observed, from other critics, those around me, and the previews themselves, the movie is designed to be a juvenile, action packed roller-coaster ride. Blaming people for going to see that is like blaming people for going to an amusement park.
I mean, who knows, maybe I'll see it, and it'll be complete masturbatory trash and I'll then be inclined to agree with you (that I'm dumb for thinking it'll be fun). However, with what I know of the movie so far, I think, as I assume most others think, it looks fun. Then again, so does jumping off a bridge, yet most people know better than to try that, but that's not the point.
I rationalize, like others probably rationalize, that I've got League for my urge to tryhard, great, small indie titles, both interactive and non-interactive, for when I need a thought provoking piece of media in which I can process for weeks to come, mainly anime, and a mind that tends to make terrible fanfiction I will never write about. Sometimes, I want to witness something I know won't affect me deeply, if at all. Sometimes, I just want to see giant robots hump eachother, and not feel bad about it, because this time, it's not some weird hentai.
Besides, if I don't slot out something completely void of thought provoking material in my mind, the important things that need to be thought about, like, say, my chemistry homework, won't really be pondered to its full potential.
