I don’t know if it’s still a problem, but I think that the teleportation works for Deadpool. It would make sense that Stryker would make him do it… can’t Deadpool, pretty much, not die? Oh, but it’s insane that he can teleport. He does it in his video game, too. 
Again, don’t know if people still hate this, but the way he looked made sense. I’m not… that big of a nerd… so, I don’t know how to explain that better. Of course, they would close his mouth as great as they can. The end credit scene showed that Deadpool was still alive, so when he was on his own he coulda just… un-did it himself… somehow. Wade was being used as their perfect lil weapon baby test subject. They probably weren’t 100% prepared for this.
 As for the katana arm things, I’m not a fan. I think it’s a cool idea. The fights looked cool with it. I think they could work with the right movie.
 I hate the laser eyes.
