I can point out a lot of reasons. But most of them are about the main character himself: <PERSON>.
1. The most obvious reason is "Humour". <PERSON> can be a pretty complex character, but one thing that is certain about him is humour, which contributed greatly to his movie becoming a people's fave. He's not only making fictional humour, as in, humour that only applies in the movie. In the movie, he makes fun of even Marvel itself, and other superheroes/movies like Wolverine and Green Lantern. The character <PERSON> (<PERSON>), also played as another superhero in the movie Green Lantern, in which he had a green CGI animated suit. In the Movie <PERSON>, he says ***“don’t make the suit green or animated”***, referring to his superhero suit, and poking fun at the suit he (<PERSON>) wore in the movie Green Lantern. This makes him a different kind of superhero, not like the "standard" superheroes that are serious and uninteresting.
2. The movie's length is just perfect. A lot of superhero movies feel the need to be over two hours long! This movie is just 1 hour 48 minutes. Just enough time to tell a story with some action and comedy without padding it out with pointless scenes
3. Deadpool contains very little racial, political and social conspiracy theories. Most superhero movies seem to have hidden political translations. 387
An example is the X-Men Franchise. It draws deliberate parallels between the oppression of mutants and that of other marginalized groups, like the blacks and the LGBT community. But Deadpool doesn't contain any such content/tradition.
4. The movie is balanced. It perfectly balances humour and drama/action, without completely overwhelming the audience with either. The movie gives you enough drama without being totally overwhelming. Most movies tend to bore out the viewers by over-emphasis of an event or plot. For example, <PERSON> suffered very much when he was experimented on. But his suffering is not forever showcased in the movie. every movie with <PERSON> (X-Men Character), who experienced the same suffering from the same types of experiments (from the same organisation too), is constantly darted with flashbacks and references to the times he suffered. In the end, it becomes depressing as the movie comes out to be a suffering story, rather than being an action feature.
Deadpool went through so much and is no longer mentally well or sane but is ALLOWED to be funny by the movie. If Marvel had gone with the tradition of their other movies, Deadpool would either be a "scary psychopath/sociopath" with no feelings. Deadpool is a unique and even uplifting portrayal of someone with mental health problems
In conclusion, Deadpool is a likable, fun , compelling and even sympathetic character. And the movie is well crafted, and that's why people love it. 387
