House of the Dead Overkill has some clever lines and fun play off B-movie horror movies, but a lot of the "funny" dialogue falls flat because of its predictability and desperation to make it racy. Either way, it's fun and does its job as a decent rail shooter.
Madworld's camera isn't that bad. It's not great, but it's definitely manageable. The game is ridiculously easy to compensate for it (until the harder mode is unlocked). Unless you start getting creative with kills, it'll get really old, really fast, but that's more of a burden on the player than the game. The game gives you the option to vary your kills... if you don't, then you'll complain it's repetitive.
