I usually give something at least an episode before I deem it unwatchable or terrible. Like, I've watched an episode of Yu-Gi-Oh, and I don't really like it very much. Same with this one anime, I don't really remember what it's called. I've watched one or two episodes, and I just couldn't really get into it. It was so strange and awkward, I wasn't even sure what the hell I was watching. Plus it didn't help that I was watching a dubbed version from Netflix. It was really awful. If I don't enjoy something, I'm not going to waste my time watching the entire series if others like it.
