The first in the series was entertaning enough and they managed to take everyhing that was good and made it better, I'd call this a thriller / comedy.
Dr.Beck has these delusional fantasies and it takes a while to figure out whether or not it is actually real in the context of the movie. To be fair, the line between an LFM movie plot and a psycho's fantasy is pretty thin to begin with and the writers play it really well. Not a spoiler, I looked for them and they still pulled it off.
His character works best when he's a mixture of someone you feel sorry for, creeps you out, and then say, 'that's evil, don't do it'. They did a better job of making his character a little more empathetic, especially the way he gets cut down by the first woman he tries to date. He acts hurt instead of exploding like an idiot like he did in one.
Oh and his bad luck, it's worse than the Coyote in the old Roadrunner cartoon. If this guy had to pick a number between 1 and 1,000 where only one of them would make him lose, he would get it on the first try. But yeah, he is a creeper but you already know that, I wish this guy would just shop for a wife in Brazil or Vietnam already.
