Though several of the twists and turns were slightly obvious at points, Happy Death Day nevertheless makes for an incredibly fun, light-hearted dark comedy slasher that beneficially uses the unique time-loop notion seen time and time again to a rather invigorating measure here.
The PG-13 rating implemented on the film itself fortunately doesn't fault it that much as the film is considerably more focused on bringing in the legitimate laughs and also giving most of the main characters the proper development they rightfully deserve in all.
The whole cast here efficiently delivers some solid performances as well, however, it is Israel Broussard and especially Jessica Rothe who give Happy Death Day an energetically upbeat quality collectively which makes this particular film all the more delightful.
