The only thing I'm "worried" about, and it's more speculation than anything, is to see how Deadpool's success will affect the future of the X-Franchise. Apocalypse is garnering enough money to be considered a hit outside the US, but Deadpool killed in domestic box office and seems to have overall raised the X-Men brand.
IIRC James Gunn expressed some annoyance about how a lot of Hollywood producer types were claiming to "get" what made Guardians so successful, and I'm pretty sure this is already happening to Deadpool (it happened to him in the comics, I remember the gangnam-style covers Marvel pulled).>>83527860>>83527896
Agreed that his performance was one of the only enjoyable bits in that movie, no doubt that he could pull off the character. There were serious doubts that Fox could end up producing a quality movie. Their big release prior to Deadpool was Tranktastic 4 and that asset for whatever collection of reasons turned toxic.
