Just going to have to disagree with almost everything that you said there and move on. They spent 5 minutes in 616. This was for all intents and purposes a self contained Deadpool & Wolverine film that had fox universe cameos and I don’t really see anything wrong with that. Doesn’t mean they won’t show up in Avengers or potentially crossover with Guardians or Thor at some point (I feel those two would be fairly natural crossovers if Marvel is willing to let a Guardians or Thor film go R for example).but this isnt just a simple little deadpool movie, this is a beginning of a new marvel era, a sort of rebirth, it might influence the marvel universe, and it was very badly written. badly structured.
thats literally the problem with these marvel projects, they are part of a whole, this is basically loki 3 but its written like a SNL skit (which is fine for comedy) but didnt do anything to grow the overall bigger story. if anything it hurts parts of the marvel universe.
yes it was funny, sure its a good time no alcohol required, sure it has awesome cameos... but its a very bad marvel project - plot wise.
The story isn’t going to win any awards but it’s also far from being poorly written.
