This Is England is on my list aswell.
Atonement, which I watched yesterday, is not. The first hour's bizarre shifts in tone and perspective completely threw me, and I couldn't recover. My mind went something like this: "Ah, boring old wartime British upperclass ennui, how about that... Wait a second, isn't that a Ben Stiller-romcom-like plot device? What, it's a thriller all of a sudden? Now it's a war movie? And how come it's almost a decent movie whenever Ikea Nightley isn't on screen, and it's abysmal when she is? And get out of town with that attention-whoring long shot."
