Five Year Engagement
I really like Emily Blunt, I could probably watch her in any film and I've loved Jason Segal ever since Freaks and Geeks. Thus, I enjoyed this movie. I saw it with my mom and we sat in the almost front row. I asked how she liked it and she said "It's different." And by the end she said "I like this movie more now". That's probably because SPOILER ALERT: it has a happy ending.
Alison Brie is also very good and has a stellar British accent and she and Emily Blunt have an awesome scene where they speak like Elmo and Cookie Monster, respectively.
Go and SEE IT.
