I had the pleasure of watching a family cry when spiderman dusted in part 1, was fucking hilarious, I laughed harder than what was socially acceptable. Part 2 I was sitting behind an annoying couple where the BF was explaining who everyone was to the GF.
Momo has major serial killer energy
I liked Kira more than ~L~ 
Who didn't? L (and his successors especially) had to constantly cheat to stay on top of Kira.

Fuck Death Note's ending, btw.
I didn't. I'm a boring fan of vanilla stuff, so I pretty much always root for the good guy. I love a good, competent villain like the Joker or Kefka, and I do like the good guys to lose sometimes (it raises the stakes and tension), but I pretty much always want the good guys to win in the end.
Also, Kira definitely had the upper hand in terms of advantages. He only had to find the name of one dude that he was constantly around. L had to narrow down the location of Kira from the entire 6 billion population on the whole planet. Sure, he had an organization of support, but the person he was trying to find could have been anywhere in the world and killed someone anywhere else in the world at any time in any way. Kira knew he would be sought after, but he still made blunders that allowed L to track him down very quickly. L was way more competent than Kira.
But yeah, L's successors sucked.
