X-Men

-The movie was largely based on a leaked script that floated around and was talked about by fans for a while. I don't recall how much was similar and how much was different, but I'm pretty sure some of the pop culture gags like Deadpool's Adventure Time watch and a Subway joke were added later.
-The opening credits with the fake titles was great, and it was a nice tease for the action sequence that happened a little bit later.
-I got a bit of a Hotline Miami vibe from Deadpool trying to save twelve bullets while taking out the henchmen quickly. Also, their numbers appeared on the back as he counted his shots!
-With the way the movie was edited/structured with flashbacks, I kinda wish all the highway stuff was more spread out over the movie instead of getting a bunch of it of right at the beginning.
-The first scene that featured Colossus and Negasonic Teenage Warhead felt exposition-heavy, but overall I liked how the characters were used with Negasonic being disinterested/dismissive towards Deadpool and Colossus acting as a foil for him.
-The sex montage is probably my favorite "aww, they really are made for each other" moment I've seen across any media.
-For those who are curious, International Women's Day is March 8th.
-It's never mentioned if the group that recruited Deadpool was Weapon X or not, they're just "a private organization".
-If you pay attention right after the fight scene where the lab is on fire, you can see Deadpool's wang.
-I would've liked to have seen Colossus try to recruit Deadpool during the flashbacks instead of him just mentioning that detail in the present.
-I can't tell if my favorite gag in the movie is intentional or a technical inconsistency that was overlooked in post-production. Deadpool gets shot in his anus early in the movie and it shows up as a black spot in his costume. When Colossus and Negasonic are talking to him later on, that black spot had a metallic color and it looked like he was slowly pooping out that bullet. However, I don't remember seeing or hearing it fall out later on.

-I liked how Hugh Jackman fit into the movie.
-Two Rob Liefeld mentions. First, his name is on a piece of paper during the opening credits and I think he was one of the henchmen in the van that pulled up next to the one Deadpool dropped into. Second, Deadpool walks by Rob Liefeld in Weasel's bar and greets him.
-There were a bunch of names listed on the chalkboard at Weasel's bar. I didn't get a good look at the whole thing, but I noticed a few familiar last names and one of them was Sheen (Charlie Sheen?).
-Fabian Nicieza has a road named after him according to a sign in the background during a highway scene.
-The X-Men Origins: Wolverine version of Deadpool found its way into the movie for five seconds.
-I wanna say the mutant with spikes on their body is a cameo of Spike from X-Men: Evolution, but it's probably just a random mutant or test subject.
-"MacAvoy or Stewart?"
-Stan Lee's strip club!
-Yay, Fox found a way to include Bob while dancing around Marvel's Hydra movie rights issues!
-If what Deadpool tells the audience about Deadpool 2 in the post-credits scene is anything to go by, I'd actually be okay with Mel Gibson playing Cable.
