Saw it last week; bloody loved it. Thrilling, very funny, full of wit and invention and lovely to look at and listen to. A proper adventure film which all ages can love. Tintin himself is a little do-goody as heroes go, but everyone around him is so characterful that that doesn't matter. Pleasingly they don't attempt to make him any more 21st century-friendly: he's still a boy detective who packs a pistol and a mean right hook.
Spileberg is way back on the case with this one: it's the sort of form he wasn't quite in with Crystal Skull- there's loads of clever directorial ideas and great jokes that the old Indy films were full of and the last was lacking in slightly; so seeing he can do it here makes Indy 4 feel a bit of a missed opportunity. There's even a bit of business with a line of gunpowder being fought over which I recognised from the Monkey King script for Indy 3.
Spielberg's so good here that he manages to out-do all four Pirates of the Caribbean films with just one short flashback sequence! It's amazing. And the Morrocan set-piece is pure genius: funny, exciting and jaw-dropping all in one. That said, the camera rarely stops moving, which doesn't always feel very Spielberg. There's a lovely bit of machine gun death through a door towards the beginning that feels like a vintage Indy-style death, though! Very stylish.
It does tail off slightly towards the end, so much so that the climax doesn't quite feel climactic enough, but the whole film has been so great up until then that that doesn't matter. Not perfect, but I'm desperate for another immediately! Looks lovely in 3D too.
