Time travel plays a huge part in Deadpool 2—without it we wouldn’t have a story and subsequently a movie.
While the sequel itself is the perfect follow up from the original, we have a few tiny issues with its use of time travel.
Here are 5 times it made no sense...
The teddy bear
When Cable's teddy bear returns to normal, it suggests that the only thing Cable's time travelling antics changed is that his family are okay.
However with all the things he does and changes, such as the amount of people that die due to the prison truck chase scene, it would be likely that he erased his own existence.
You can’t even justify this with the 'you cant change the future' rule because if whatever happened, happened, he wouldn't be able to save his family in the first place.
The music box
The music box that Ryan Reynolds plays with in the early part of the movie is homage to the death scene of Logan.
Logan the film is set in 2029 and Deadpool is set in the current day, so unless Deadpool himself can time travel how would he know what the death scene of his arch enemy looks like to make a music box resemble it?
Time traveling X Men
The X Men versions that are secretly in the Xavier School are all from the X-Men Apocalypse film. Which is set in 1983. When beast closes the door on Deadpool we have already seen Cameos from Quicksilver, Charles Xavier, Cyclops and Beast himself. But the issue is they are all the 1983 version which means they either time travelled for reasons unknown to the viewer, otherwise the writers forgot to mention it.
Cable choosing the wrong time
The effort Cable puts in to killing Russell during the movie just made me wonder why he didn’t go back further, adopt him when he was a baby orphan and either take him to the future or just off him then.
Given how hard Deadpool has to work to get Cable not to kill Russell as a teenager, it probably wouldn’t be out of the question for Cable to do the deed to an infant.
The final scene
Deadpool goes back in time again in the post-credit scene to save Vanessa. If he was going to go back to anywhere, surely it would make more sense to go back to way before the first film, before he had cancer and warn himself?
