Why does Deadpool need to be serious?

Rating: 6/10 (23 May 2018)

First off, the movie isn't as bad as some reviews admit here, but definitely not a 8.2(!). So make sure, that you build your own opinion, that's the most important thing.
As I scrolled to some reviews here, I was pretty surprised that no one mentioned the major issue the movie has. Where there are few good and even great scenes, like the parachute drop, there are also some really bad one's.
Why does Deadpool need to be serious?
All the background plot with his girlfriend and with "making a baby" was just terrible. First off, Deadpool is insane, why does he need real reason to do anything? I don't want that Deadpool is getting treated like other super heroes. That's unnecessary. I just want Deadpool being Deadpool, weird, violent and crazy. DP doesn't need a "tragic Subplot" that shows his motivation. I couldn't care less about Vanessa (girlfriend). There is unironically one or two scenes that should be sad and tragic. How am I supposed to feel affected by that? Every character is forgettable and exchangeable, besides Deadpool.
What I want is: A Plot that is just ridiculos and that DP makes fun about it, violence, 4th wall breaks, action, dark brutal humor, completely crazy storyline etc.
Indeed, there was some of this, but sadly not enough.
I will not start with the kid, the huge plotholes or with misplaced jokes. There are plenty other reviews that cover these topics already.
I'll rate the movie 56/100
