I think Kong: Skull Island is one of my favourite films of all time. It’s a big, meaty monster movie with plenty of focus on the monster(s); Kong is not the footnote to a human story, but an integral part of a story that occurs in a natural world. It also strikes the perfect balance of fun with the straight faced delivery required to carry off a giant ape bashing giant dinosaurs in the face.
It also has a post-credits sequel hook, but you don’t need to watch that or the lightly-linked precursor Godzilla (2014) to enjoy it. This is the holy grail of shared-universe films: each one standing on its own, but quietly accentuating the others when taken in wider context. This is world-building done right.
