Overrated nonsensical melodrama

Rating: 1/10 (18 January 2017)

This movie was on TV this evening and I decided to watch it partly because it has a reputation as a decent film, and partly because there was a joke that referenced it on "You're The Worst" this season and I wanted to get the backstory.
Since it was on regular TV, it was obvious that some bits had been cut out and some dialog had been changed to get around the R rating, but I'm pretty sure I got the gist of it. And it baffles me that anyone thought this was a great movie.
Others have done a great job of pointing out all the plot holes here on IMDb (as I did to my wife while watching it), but not many have mentioned how over-the-top melodramatic the story and acting were (as my wife did to me several times while watching it), to the point of near self-parody.
Speaking of the plot holes (SPOILER ALERT), I'll just mention that my favorite is that the wife is DRENCHED in blood after killing her "alibi", drives all the way home that way (without calling for help), is taken to the hospital, examined by doctors, sedated, questioned by the FBI and police and taken home again...and is STILL drenched in blood, finally showering it off at home what must have been hours later. What the heck? How was that supposed to be even remotely believable?
But maybe, just maybe, despite all that I could have found it in my heart to give this a 5 or 6 rating (after all, it did help kill three hours of an otherwise dull evening), IF IT HAD HAD SOME KIND OF ENDING. Seriously, I was really curious about how they were going to resolve this whole thing - I expected either the husband to kill the wife or vice versa, but nope. Affleck's character decides to just live fearfully and suspiciously ever after with his psycho wife, roll credits. Wow, what an anticlimax.
The movie probably still deserves a 3 or 4, but I'm going with 1 just to try to bring its ridiculous 8.4 average down a bit.
