This movie brings together all your favourite heroes (and villains) to battle against the mad titan Thanos. It is part of the MCU (Marvel Cinematic Universe) so don't watch it if you haven't seen any of the other films. If you have seen the other films (whether you've watched them in release order or chronologically) this is the big one you've been waiting for. Thor meets the Guardians of the Galaxy, Spider-Man meets Doctor Strange and some of the other Avengers battle it out in Wakanda. I don't want to spoil the film too much but the ending will shock you (so be prepared for a big surprise) and this is one of, if not the strongest, entries in the MCU so far (and I am writing this in mid 2021). You should also definitely check out the trailer online (it'll get you hyped for sure). If you're looking for a parents guide, here's what I think: Language: The normal for a Marvel film, around the same as Captain America: Civil War (mostly sh*t, son of a b**ch, a**hole, d*ckhole). No F bombs. Violence: This film is allot more intense than what you might expect and their are allot of action sequences right from the beginning. Their is a large focus on death, loss, grief and mass murder. Their are 2 major sacrifices made which are brutal but are justified as "necessary". But the violence is average for a Marvel movie, there is just more of it. Sex: There is kissing but absolutely no sex or nudity is implied. There are relationships between humans and androids and aliens (Wanda and Vision and Star Lord and Gamora). One of the aspects of the film is saving the people we love or care about the most. There are great role models (The Avengers) but convincing villains, making the difference between good and bad a bit blurry. All in all, I think anyone older than 10 could easily handle it.
