Actually it is finally here - with the last movie in the series ... which coincides with being the last book that is being adapted. Now I have not read the books, that are obviously aimed at teenagers. So I am not really the target audience. But I have seen the other movies too ... and I sort of liked them. Through all the mayhem and nonsense they make you go through, they are likeable.
Yes time travel has never been handled with less accuracy, but you just should give it a pass ... if you don't think you can do it, you'll be annoyed all the way through ... why does a vaccination of a famous person not change the future, but an accidental meeting with Shakespeare make him come up with one of his best known quotes (to be or not to be) ... the latter is meant to be just a funny anecdote ... but one that is also a story element of sorts ... again do not overthink it, do not try to make sense of it ... you'll be better off. I won't rate the "acting" either - over the top and all that. Cut it some slack or don't watch at all.
