I enjoyed it too. Must admit when it finished it did have a slight feeling of ‘What did I just watch?’ but I pretty much enjoyed every scene, even when some of them were ridiculously slow 
. DiCaprio and Pitt are such great actors, I agree might not be their best films, but they’re so entertaining to watch.
The movie built up well to the night of the killing and I was fully expecting it to go according to real events, what actually happened was proper wtf 
the flamethrower scene had me in stitches, especially the dialog with Jay afterwards. “I happened to have a flamethrower in my shed”.
