The film follows the story of Maura Ellis (Amy Poehler) and her sister Kate (Tina Fey). The two are as close as sisters can get, despite having rather different personalities. Kate spent her teenage years getting drunk and partying, whereas Maura was the one who made sure nobody got hurt and that the party was under control the whole time. Now, their parents have decided to sell their childhood home, and they are not okay with this decision. Upon finding out, the two begin to reminisce about their youth, and it's doing this that gives them the idea to throw one last house party before it's sold off for good. This time around, however, their roles are reversed, Kate becoming the "party mum" and Maura letting her freak fly. What on Earth could possibly go wrong?
The supporting cast do their best, and they all have their moments to shine, but none manage to be nearly as consistent as Fey and Poehler. Maya Rudolph is the film's antagonist. She's the childhood friend of their characters and she's back with a vengeance, hoping to shut their party down. Her character is as clichéd as they come, but she gets a few laughs. They're never big laughs, but I did chuckle from time to time. The same can be said with Poehler's love interest in the film, played by Ike Barinholtz, as well as John Leguizamo's character.
To sum up, Sisters is a mediocrely made movie that doesn't have a lot going for it aside from the hilarious leads and occasionally chuckle-worthy supporting cast. Yes, I enjoyed this movie more than The Revenant. I don't care what you think about that.
