Finally got round to watching this... enjoyed it mainly. Great performance from Sandler, he looks completely different - in fact he is completely different - from last time I saw him. Which is partly cos last time I saw him was about twenty years ago and I turned him off saying I never want to see that person again.
Lots I liked about it, lots I didn't though... I guess cos this thread is twenty-thousand pages long that most people have seen it so it's not a spoiler to talk about the end. I didn't buy the bit when Pauli Walnuts shot everyone, I think it would have been much more in keeping with everything so far, and more fun, if there had been some kind of reconciliation based on the won bet, I think that could have been the right ending and would have fitted better with what went before.
Bigger problem, I really liked the first scenes when I couldn't understand what was happening and (this goes along with what I was saying in the other thread about realism and so on) as it went on, the more understandable it became, the less realistic... the tenseness was exchanged for comedy. I think that may be some kind of paradox of realism in films - reality is too hard to understand so realism and narrative tend to be enemies.
As an aside, I very much like the guy who played Arno. He was Bernie Sanders in Succession but I first saw him in Wonderland Avenue as Eddie Nash (I think he's called). Grimly fascinating film about a brutal and - to me - interesting bit of - almost - hollywood history, worth checking if you get a chance.
