This Mann can direct!
This reminded me a lot of Safdie Brothers. Of the Michael Mann movies I've seen, he has never been more stylish. I loved the neon vibes, the synth score, and the slow burn plot line.
If you ever wonder why James Caan didn't have a bigger career, just look up a list of the parts he turned down. He likely had the most mismanaged career of the 70s, yet kicked off the 80s with one of his best performances. He is absolutely electric! Going back to the Safdie Brothers, he reminds me a lot of Pattinson in Good Time or Sandler in Uncut Gems. He's brash, and irrational yet he is up against a greater evil so you're 100% on his team.
I wasn't very invested in the plot, especially in the first half, but it really picks up steam near the end. I was really impressed with the final 15 minutes!
