Hmm... I also like watching JDrama's, my personal favorites would probably be the Hana Yori Dango live action, I also love watching Gokusen live action season 1 and season 2, Detective Conan's pretty good too
I think Death Note's also well made, Ryuuk looks so much like the anime Ryuuk and the way they changed the story line's also nice
Prince of Tennis live action, the special effects' all right, they kinda got the characters' special moves
the guy who played Tezuka Kunimitsu--Shirota Yuu's gorgeous
I love him..
But they kinda made the storyline fast, it's more like the summary of the anime from the start until the Hyotei arc
Same goes for death note live action... But I think they made the live actions fairly well, I mean, they can never exactly copy the anime, there are limits to reality but nevertheless they did a good job on these
