Part 2 is even better than the original!!!!! I liked it so much I just ordered the Blu-Ray set! Part 1 spent a lot of time introducing the story and the rules and characters, etc., but with Part 2 we already know all that shit so they bust in balls out from the very beginning and it's a non-stop roller coaster ride the entire movie!
You already know how at the end of Part 1 Kira killed his girlfriend to gather enough sympathy to be asked to join the task force well now he's in, but even he's in for a surprise when a second Kira shows up and this one has "the eyes" that the god of death spoke of earlier. I'm not going to give any more away, but it was very exciting. Highly recommended.
My one and only complaint (besides Erika Toda not getting naked) was the song by the Red Hot Chili Peppers. What the fuck is that shit?! Yuck!!!
