Re: X-MEN: FIRST CLASS - Grading+Discussion **SPOILERS!**
I'd rather not see the characters run into Wolverine again until he joins the team. That said, I wouldn't be against a cameo if they could find a way to do it without any of the team members, and have it make sense.
Over the course of many encounters and many years, I have successfully developed a standard operating procedure for dealing with big, nasty monsters. Run away. Me and Monty Python.
