For a Tubi original movie that was free to watch, this was surprisingly good. I won't give away any spoilers, because with a title of "Guess Who", you should know there's going to be surprises along the way but it's best to see this without knowing too much beforehand.
I never heard of Mummering before watching this, but apparently it's been a tradition since the 1800's and is actually a real thing. I'm surprised that a horror flick hasn't been made with this kind of plot until now because a tradition like that just screams for one.
I thought the plot and acting were both good here and the film kept me interested until the end, and I thought the final scenes were pretty intense...(don't worry, no spoilers will be written in this review.)
I especially enjoyed the lead actress who played Kaitlyn and would love to see her in more horror/slasher flicks. I think she has the perfect look to be a great "Scream Queen" actress like Jamie Lee Curtis was back in the day.
I thought she was really good as the innocent girl thrust into a nightmarish situation and felt the actress displayed lots of charm and charisma. I'd love to see her again as the "Final Girl" in more of these types of slasher flicks.
I thought rest of the actors were also good as well as the production quality and pace of the story. If Tubi continues to make more original horror flicks like this, I will continue to watch them. (but then they'll probably start charging us to watch so maybe I shouldn't say that lol) I give this film a solid 8 and recommend especially to other horror/suspense fans. I really enjoyed it.
