It's interesting how people have such varying opinions on this movie. I for one disagree, as I found it to be very different for the first one aside from the humor, and even there you've a got a very different brand of humor in the first act. I also thought that one thing they doubled down on in this one was the emotion. I found it to be surprisingly touching and deeper than I expected.
Anyway, Ryan Reynolds has already confirmed that what excites him about X-Force is that it's going to have a very different tone, so I imagine it being a more straight forward sci-fi action movie with Deadpool as its comedic centerpoint.
