I watched the whole anime, thinking that it was going to get better in some way. Unfortunately, it just kept on spiraling downwards. The animation isn't that great, and I wasn't a big fan on how the characters were drawn either.
I know most people are probably taking into consideration that Harry was just a really, really indecisive, almost annoyingly awkward character. I'm sorry, but if the main character acts like that, it's almost impossible to like the actual show. I don't think I heard Harry say anything substantial the whole entire time, and there are episodes where the longest thing he says is "I would like a roast beef sandwich" or something like that. The rest is usually some sort of gasping or name reiteration. There's not a lot of redeemable qualities of the guy with the most screen time, which is one of the reasons why the anime tanks.
The concept of the story is actually very interesting, and the damaging effects that comes with Harry using his psychic powers are intriguing. But after a while, it's just really hard to watch through hours of people staring at one another and trying to keep up with what's happening in the crazy story line, only to have a vague conclusion after enduring everything that went on. I often wonder why I finished the anime.
