I saw it in the theater, and I was slightly disappointed. The original, I felt, was simply better, tighter, funnier, and it made more sense as far as Deadpool's power to regenerate.
I'm sorry, but if he blows himself up by lying on barrels of fuel, there shouldn't be much left of him to regenerate, and what's left of him should be burnt and unable to regenerate. Also, being ripped in half by Juggernaut should cause, at the very least, some major blood loss and death.
This is not even counting that he blew himself up in his apartment, which is in a building that is occupied by other renters, so he destroyed his apartment, and theirs, and perhaps the building itself, leaving a lot of people and perhaps families homeless. If you want to go, go, but don't take everyone and everything with you. That's crap, to be polite.
Having said that, I like this version of Deadpool 2 better than the one I saw in the theater. The scenes they put back in actually make the movie better, funnier, more coherent. It was a mistake taking them out.
In the theater, I thought it was basically a movie in 2 halves. The first, before they jump out of the airplane, was okay, so so. After that, I thought the humor was great and the action fantastic. In this Blu Ray/4K version, with the added scenes, I think the movie is a lot better from beginning to end.
The original is still better though.
