Why was Colossus in this movie?
He was probably my favorite character and it was cool seeing him brought to life with some decent CGI, but why was he in it? Is he a regular in Deadpool comics? Do the two characters have some special connection? (I wouldn't know, I never really followed Deadpool.)
As I said, I enjoyed seeing him in this, but he seemed a bit extraneous - like they just wanted to stick another well-known or X-Men-connected character in there. But he didn't seem necessary to the plot or like he and Deadpool had any relationship beyond just being acquaintances.
I was glad that they finally made him Russian - true to his comic roots (unlike the way he was portrayed in the various X-Men movies - the actor in those movies looked great in his human form, but he had an American accent, with no mention that he was Russian). The only thing that bugged me is he looked and sounded a bit too old. I know it's hard to tell with him being metal, but he sounded middle-aged. It would've been cool if they showed him transform once so we could have seen that Piotr is a young man.
