“Happy Death Day” (** out of four) was a not-bad horror thriller about a bitchy college student (Jessica Rothe who looks like a young Britney Spears) who finds herself reliving the day of her murder over and over again a la “Groundhog Day” until she discovers her killer’s identity and also learns how her past behavior affected others. Undeniably repetitive and silly after a while, as all these time-repeat movies are, but has enough scares and laughs to make it watchable for horror fans. Rothe’s first-rate performance helps a lot. Funny enough, one of the characters actually asks her at the end “have you ever seen ‘Groundhog Day?” in order to compensate for ripping that movie off.
