It's a good sequel, but not very good otherwise

Rating: 6/10 (19 May 2018)

It does manage to do what most sequels don't: follow the original, stay "true" to it, but introduces some new stuff and lets go of some old stuff.
But, it has many of the same problems as the first movie, there's no improvement here. If you liked the original, you'll like this one. And if you didn't, then you won't.
There's much less real breaking of the 4th wall, which makes this less of a "Deadpool" thing. But, since it didn't really work in the original, I guess that could have been expected.
Sequel goes more for trying out jokes and more one-liners, sacrificing the plot, which is ridiculous anyways, so no loss there. It has a rather even pace of a good joke about ~15 minutes. In the meantime, though, it can get kind of annoying... like "please, stop trying, you're not doing so well". While these interludes are not as fun or funny as intended, they are somewhat interesting.
Zazie Beetz is very charming, which is a nice touch - basically everybody else is somewhat uncharming. Maybe they could have played a little more on that.
There's one interesting surprise at the end - the slow performance of the 80s hit "Take on Me", which works out great. The song was originally something completely different, that's why the surprise is so big and why it works so well.
It still doesn't really expose the superhero genre for all its silliness, that's obviously for some other movie to take on. Deadpool just tries to have fun and, at times, succeeds.
