Just watched The Secret Agent which means I have now seen 7 of the 10 Best Picture nominations (I'm missing Hamnet, Train Dreams and Sentimental Values). It won't win, but it's by far my favourite of the 7 and the only one that I think would actually be worthy of winning in what I consider a pretty weak year. It's long (2 hours 40), messy, and for the first hour doesn't seem to be going anywhere, but there are tons of good performances (the lead Wagner Moura is nominated for Best Actor and IMO should win), the characters of whom there are many are all written and acted superbly to be far more interesting and multi-dimensional than most movies manage, and the cinematography and score are absolutely gorgeous and absorbing. I promise it's worth sticking with the slightly slow and meandering first hour because once the strands start weaving together it becomes absorbing, and it's one of those movies that definitely deserves a rewatch because there's a bunch of stuff I'm sure I'll notice the second time round.
Big recommend on this. Really liked it.
