Yeah... Yeah. They try to have it both ways, too. After all the Deadpools make their dramatic entrance, Deadpool Prime makes a speech about multiverses being played out and haven't we had enough of this already, etc. Yes, but you're still doing it. But because you're furiously winking and nodding at the audience, that's meant to bring it all back around to being entertaining again? Nope.
To be fair, it's all just setup for a prolonged murder montage that's actually pretty fun, if ultimately meaningless. Because what is Deadpool known for? Getting back up after being horribly mangled/mutilated.
