The Melancholy of Haruhi Suzamiya - Amusing but the episode order was quite messed up. The male protagonist was great character but CLANNAD has similar one and beats him in comedy.
I didn't like it at first.. but i think the order it was originally aired in really made it better. I left out episode 4 i think (the baseball one) and ended up watching it last and I really like that one as a last episode.. i haven't watched them in DVD order yet.. not sure if i want to since the TV order was perfect. Heard along about CLANNAD.. guess i'll have to check it out.
Death Note - gets boring after ******** dies. (no spoilers right ^^)
It changes but i don't think it gets boring.. I think the whole resolution was excellent because they didn't dig themselves into too much of a hole. I think they stopped cluing you in to what each side was fully doing as much as they had been previously because that ended up being a lot of the end and maybe that is why you say that.
Welcome to the NHK - Hilarious if you know the background a bit (first episode doesn't tell it clearly enough.)
? Background of what ? do you mean like the manga?
Higurashi No Naku Koro Ni - I've seen till the 8th episode and that was enough. Quite sick series. If you like that kind of stuff you probably love MPD Psycho manga.
You definitely have to go to the end. Its not too long before the whole damn thing stops making sense and they don't even really start to touch on why that is until the last few episodes... couple of scenes though.. definitely not for the weak hearted.
GotF really let me down. The animation was good.. but you are set up for the end in the very beginning or from the box summary even. The trip there didn't really do anything for me.
Also didn't care for ninja scroll when I saw it.. maybe because that one woman kept taking breaks to get raped every couple of minutes or something.. probably re-watch it eventually.. but i think both of those movies are a bit over-rated.
