A former Special Forces operative turned mercenary Wade Wilson (Ryan Reynolds) is subjected to a rogue experiment that leaves him with accelerated healing powers, adopting the alter ego Deadpool.
Let's get the easy part out of the way first: Deadpool is an amazing movie. In his cinematic debut (Yes, this is his debut. X-Men Origins: Wolverine does not count. We don't talk about that movie.), we get quite possibly the most accurate comic book adaptation we've ever seen. This is the Deadpool that fans have been waiting for since he first appeared.
Rhett Reese and Paul Wernick wrote this movie so close to the character that it almost felt like we were actually watching a Deadpool comic book being played out onscreen. I do slightly wish that they had included more of the voices in his head. They were alluded to in a flashback to where he is first developing his powers, but after that, they were never mentioned again. It is understandable though; it can be difficult to write the voices-in-the-head without being corny and cliche about it, and it didn't take away from the quality of the movie, but I did kind of wish that they were a little more present than they were. The layering of the story was also a bit strange to me. At least half of it was cutting back and forth between backstory and present day, leading up to "and that's how we got to where we are now." It wasn't bad storytelling by any means, but it just felt a bit odd. I was afraid at first that they were going to screw up Deadpool's 4th-Wall breaking and either seriously overdo it, or seriously underdo it, but they got it perfect. His 4th-Wall humor was one of my favorite parts of the movie.
The directing was awesome. It, again, fit the character super well. We got some really well-performed action sequences (some of the most badass fights I've seen in recent films). This was also one of the most impressive directing debuts I have ever seen. This was Tim Miller's first major picture, which is super impressive to be directing such a movie that is so unique on pretty much every level, especially with a character like Deadpool.
The makeup, special, and visual effects were awesome, as to be expected in a superhero movie. Colossus (Stefan Kapicic), who was completely CGI through the entire thing, looked great throughout the movie, as did Negasonic Teenage Warhead (Brianna Hildebrand) (Coolest. Name. EVER.), Angel Dust (Gina Carano), and, of course, Deadpool himself.
The acting by everyone was great. Reynolds, Hildebrand, Kapicic, Carano, and even Ed Skrein redeemed himself after Transporter: Refueled. TJ Miller was absolutely brilliant as the extra-comic relief. You can tell just from watching the movie that all of these actors really care about their characters and they embodied them so fully that I already need them to all be back for Deadpool 2 (SPOILER ALERT: that's happening).
Overall, Deadpool is a fantastic superhero movie, and just as a movie in general. Deadpool, Ajax, Colossus, NTW, and Angel Dust are all badass and hilarious. I almost crapped chimichangas I was laughing so hard. After watching it though, it is fairly easy to tell that it definitely had a lower budget than most superhero movies, but they did pretty much everything right with what they had. The writing, directing, and acting was great all the way around. The storytelling was a bit odd, but was by no means bad. This is the Deadpool we've all been waiting for. It is Fox's most comic-accurate movie to date, and almost undoubtedly their best one yet.
