I think my main problem before watching this film is I despise Ben Aflleck so was not looking forward to the fact he starred in it, let alone co wrote it. Thankfully he was hardly in the movie and lets be honest Damon probably wrote most of the film so I am just going to pretend Ben Afleck had nothing to do with the movie.
Overall it was a good film. Williams, Damon, Driver and Skarsgard were all great, and it was nice to see Williams in a serious role and different from his usually comedy parts. I was intrigued by most of the characters; strangely I liked Skarsgard and Williams more together and Damon and Driver together more than Damon and Williams characters.
I liked it and Damon did a decent job on the script, but I found myself getting bored towards the end,plus with the fact Ben Affleck (his character had no purpose at all in this movie) was in it I rate it a bit lower - 3/5
