umm... good?
I mean, the acting was great, the story was interesting throughout the film - cinematography was decent.
The ending... a bit unclear.
Spoiler question ----
I mean... OK, from what I can tell, the dude is nuts - his memory plays tricks on him and he should definitely get a brain scan. At the same time, the dude is also into screwing his students - yet, his wife's reaction to his previous cheat is odd - why are they still together? And she said she didn't want to move again, which suggests she's OK with him doing his thing, if it doesn't cause them to move. Her reaction is odd at best - and I wish there was a better explanation for it.
