I think the only anime that i've rage quited was Blood +, & that was because even when something was happening it was so damn boring. T_T
I liked Blood+ but I do indeed remember a boring arc somewhere in the middle haha. It's hard, but if you stick with it, it's pretty good.
I actually liked the mind gameyness of it, I just hated the characters. I should also clarify that I rage quit the rewatch of it, I watched it in like 2006 I think and forgot most of it, so I went to watch it again and got annoyed at the characters too much to continue like 10 episodes in
I didn't rage quit bleach even though I probably should have. I think it's going to end in the next few months from what I've heard so might as well finish it. bleach is mostly ok when it's not filler but the filler is SO bad. I'm not going to start watching any long anime that obviously will have filler like that now though, I like things more concise
I didn't like the weird part with the real life images, not to mention some weird creepy ju-on s*** where there was a dark face and an eye opens up. I was watching that in room in the dark. Creepy as f***. The characters are weird indeed - a bit angsty too. I don't know whether to give credit to the creator for trying something unconventional or to just take it as it is; I read the ending came to be due to a mental breakdown or something of the sort.
Also, I rage quit bleach 2 or 3 times. I came back to read, caught up, got tired of waiting, got tired of filler, rage quit some more, went back, more rage quit. I'm off for good now. As for Naruto, I liked it more and I wouldn't say I rage quit as much as plank that **** waiting for it to finish so I can read as fast as I want and skip over fillers. The only thing I hate about waiting is that I tend to forget where I left off and what happened. It requires me to go back up to 5 chapters just to remember stuff.
I also like things more concise. I like to watch anime that's already done and preferably not 100 episodes unless it's THAT good. Also, I rage quit Katekyo Hitman Reborn. I hate the main character in the anime so much. Guy has a ***** - man up foo!
