Following Spilt & Get Out, Universal Pictures & Blumhosue productions continue their successful 2017 horror run with their latest release Happy Death Day. Tree Gellban (Jessica Rothe) is your typical college sorority girl experiencing the highs & lows of college life.  As Happy Death Day opens up, Tree wakes up in the dorm room of Carter (Israel Broussard) who she instantly blows off, despite Carter's good nature. Later that night, which happens to be her birthday, Tree is murdered by an unseen assailant. The next day, Tree wakes up and begins to relive the same day of her murder with both of its unexceptional details and terrifying end until she discovers her killer's identity. Earlier this year we saw two films, the Marlon Wayans Netflix comedy Naked, and the teen angst drama Before I Fall. Both use the protagonist trapped in a time loop as their central plot device to mixed results, however Happy Death Day doesn't make the mistake the two former films did. The script is smart, the kills are fun to watch, the humor is sharp and the reveal of how to get out of the time loop is a satisfying one. While Happy Death Day does have a PG-13 rating, don't let that deter you from seeing the film. Similar to 2015‘s The Final Girls, Happy Death Day fully embraces the PG-13 rating in a winning campy sort of way, which works in its favor. Rothe, who had a small role in last year's La La Land, gets a chance to shine in the lead role. Tree's journey & character are from stuck-up sorority girl, to victim, to detective is a believable one.  As Tree begins to evolve, so does her relationships with those around her. Rothe and Broussard also have a great chemistry, and I found myself rooting for Carter to get the girl in the end.  The rest of the cast doesn't have that much to do outside of newcomer Rachel Matthews. As Danielle, the leader of the sorority, Matthews manages to steal every scene she's in in classic mean girl fashion. I wouldn't mind seeing Matthews in another slasher flick, as she has the mean girl character trait nailed down pat. The film isn't without its flaws though, as the third act includes an unnecessary subplot involving Tree's father. I could've done without that entire segment of the film, and replaced it with more another death scenes for Tree, or Tree playing detective as that is when the film is the most fun. Writer Scott Lobdell & director Chris Landon, who previously helmed the guilty pleasures Scouts Guide to the Zombie Apocalypse and Paranormal Activity: The Marked Ones, have crafted an entertaining time paradox flick mixed with a slasher, fused with good old fashioned who done it.  Lobdell & Landon never make the mistake of over thinking the premise and given that this is a PG-13 rated slasher, Happy Death Day will be sure to give its intended audience just what they're looking…
