I've even heard there's a movie in production, but don't get your hopes up. Even if it does come out, films these days have a habit of letting you down.
Anyway, if you like tactics and strategy - this is another anime for you. The mental back and forth between Yagami and the antagonist, L is full of tension and is very engaging. There are a few great twists, but as usual - the manga is better than the anime.
Some of the characters are epic and awesome, I found myself rooting for L instead of Yagami. Ryuk the death god was amusing and a little cryptic at times. The art is well drawn and animated, and in high quality the graphics are some of the best. As always, watch the subbed version instead of dub. Dub sucks. Bad voice acting central, thank you for wasting my time.
