Eh I was thinking about this the other day, honestly I enjoyed it, I didnt love it, I really thought the first 15 or probably less eps were amazing and set up the anime for something amazing, and then it shoots of. Misa was an annoying addition, but I guess needed, then the evil corporation which felt like filler, L dies, add 2 more new Kiras, Mello ad Near were decent but still (and I liked Near, but im saying in terms of overall fanbase). I do incredibly hate it when people call this anime intelligent or the smartest ever, so stupid. You cant call an anime where the chracters apparently come to a conclusion that is impossible to arrive and still come out right, an example is how L immediately knew Misa was the second Kira, great telepathy powers. The animation wasnt amazing, it was good, bit nothing breathtaking, the soundtrack, aside from L's theme and the second OP, easily forgettable.
All in all I liked it to a certain point, even though watching the last 10 or so eps felt more like a chore than anything, but I still think its insanely overrated, borderline Naruto id even say.
