CRAP

you bore me.

Declaring it crap before having seen the movie is premature. Though, admittedly, I could not even get through the trailer myself... so probably not a good sign.

Go check it out, I enjoyed it (being overly drunk while viewing it and having a beautiful stranger sitting next to me might make my opinion bias?) Overall it was fun, interesting, and the gorgeous gal sitting next to me started talked technology and DARPA conspiracy theories after the film and invited me over for wine. I will forever LOVE this film, maybe because of the post activities, but I will never forget it, the combination was magnificent

The marketing campaign weaves back and forth between "non-existent" and "grossly misleading". (Fortunately in this case all the mis-marketing doesn't mean the movie itself is bad.)

There's the poster, which as the OP noted is very easy to completely misinterpret.

There's the trailer, which is interesting in its own right, but doesn't at all describe the tone/feel of most of the movie.

And there's the common synopsis that the film is about some guy's affair with his best friend's girlfriend. Sorta ...and sorta not. In actuality the film presents this "affair" as largely imagined/hallucinated (but with real-life fallout effects anyway). -- I can understand the motivation to "simplify" the story rather than presenting its full complexity in the marketing. But this goes too far, misdirecting viewers away from the whole point of the movie.
