Given the budget and the constraints placed on this movie, and the fact that its only real star is Ryan Reynolds (because that's all they could afford?), it's understandable - to some extent - that the secondary characters didn't really get all that much to do. But as a result, a lot of them felt kind of wasted and - vastly underused - in their parts. Aside from Wade Wilson, Deadpool himself, the rest of the cast - with the possible exception of Ajax, purely because he's in a lot of scenes and therefore lingers in your memory in the aftermath (to a degree) - fail to leave much of a lasting impression. T.J. Miller is a great choice for Weasel, but the movie doesn't really do anything to cement his friendship with Deadpool in our minds; Morena Baccarin's Vanessa only really gets one worthwhile scene, and then she's used as a mere plot device for the rest of the picture; Gina Carano, as Angel Dust, gets nothing interesting to do except throw a few punches. Deadpool 2's mission, should it choose to except it, is to make these secondary players far more three-dimensional characters. Give them actual stuff to do, as opposed to "sit around" or "be rescued" or "get into a fight." In a franchise that should be embracing these types, deconstructing them and therefore bringing them to life, poor characterisation isn't forgivable. Deadpool 2 need to focus on everyone - not just Deadpool.
