Now my DPFR (Deadpool Fanboy Rage) has subsided, I will give my opinions.
It was average. The first part of the film was well done I thought, general superhuman fun stuff on a par with probably the first X-film. The scenes with Team X in Africa were cool, Wade was how Wade should have been, Victor was a barely contained psycho Logan was as Logan is. Logan leaving for a peaceful life was fine and him going mental when he thinks Victor had killed Silver Fox was cool. In all honesty there was nothing bad about it up until a little after he gets the adamantium bonded to him. The film just suddenly fell apart with random plot contrivances and general bull****. Plus Gambit, who I generally dislike anyway (although his fight with Logan in the alleyway was quite cool, and when Logan elbowed him in the face was quite funny).
Then comes my major issue with the film, the part that caused my previously mentioned DPFR.
WTF?!?!
Why did they feel the need to do that to such a popular character?? Wade in the beginning was well played, Reynolds had him perfect, a sarcastic joker who is pretty damn badass when it comes to it. Then they shuffle off Reynolds and replace him with a stunt double with a lot of makeup on.
Honestly I would have had no issues with giving 'Pool teleporting powers, he briefly got them during Cable and Deadpool after fusing with Cable, and has a teleporting device anyway (essentially its exactly the same as the movie Spider-Man having organic webshooters thing). The blades were silly, they should have just left him with his katanas from the beginning (side note - loved the comment Reynolds-Pool makes about pulling out the swords at his ex-girlfriends wedding). The cyclops power was just ****ing pointless and unnecessary.
AND WHY THE HELL DID THEY STITCH THE MERC WITH A ******* MOUTH'S MOUTH UP?!?!?!
The only point for it I could see was that offhand comment just before the fight where Logan says something like "Well, I guess they finally found a way to shut you up.."
How much cooler would it have been if during the fight Deadpool was constantly talking and joking, considering he wasn't in control of his body, so just kept talking on and on?
The secret ending helps a little with my rage, but only if being beaten down removed all bar the healing factor from him (and maybe teleportation).
