Of course; I know this is a Deadpool movie after all. I wasn't expecting Oscar-worthy dialogue or real moments of emotional poignancy, but still...it was disappointing none-the-less.
It can still be Deadpool and Wolverine without trampling on the other X-Men characters. It makes me nervous about how Feige & co. will handle non-Wolverine characters moving forward. This was the MCU's first opportunity to play around in the Fox sandbox and instead of doing any course-correction, they doubled-down that Wolverine is/was the only mutant that mattered (and, now, Deadpool too).
Even if Halle, Famke, and James all said 'no' to cameo appearances (which I highly doubt), I still don't think the script choice to make Wolverine seeking redemption for dead X-Men (again) was the way to go.
