I also attended a viewing in Chicago (I was dragged along). I'm British myself, I love edgy humor and good writing, I didn't find it here.
Virtually the entire audience were die hard Robert Pattinson fans, some even wearing the T-Shirts - I'd never heard of the guy before that day. I'm pretty sure he could have starred at a wall for 2 hours and still got 10 stars from a lot of people reviewing.
The whole thing is very amateurish, you can tell it's a festival kind of movie, and in this case it isn't a good thing. The comic timing is terrible which makes it really hard to laugh at anything, it was more cringe-worthy - although again, in a cinema full of Pattinson fans he merely had to make the slightest gesture and the place was filled with roars of laughter – I was left just looking around in disbelief!
Good enough concept but an absolute fail on the execution side. I very much doubt this is going to find a distributor, as they see exactly what I see – And with the same lack of bias (i.e. not being in love with the lead actor!)
