Amazing film! Literally two hours of references, fourth-wall breaks, digs etc. Loved it. End credits scene was fantastic and hilarious.
X-Men cameo was great, was awesome to see Juggernaut (and Deadpool being a "fan" was brilliant), and Cable was fucking badass. The countless MCU references and DC digs were fun.
All-round if you're on the button with a lot of the inside jokes etc, this film is brilliant.
