I followed the Death Note manga week by week. So many cliffhangers! Twists and turns each week! The Light and L tennis match is awesome indeed. I stopped right after the episode where that was shown in the anime. Maybe I was satisfied having seen them play tennis back then. XD;

The second half of the anime is pretty compact. I was afraid that I'd find it super rushed, but it turned out okay for me. I enjoyed it. (or maybe I just forgot enough details that I wasn't sad about stuff that was cut out, haha)
