This was a mixed bag for me. There were some successful aspects but more overwhelmingly unsuccessful I think.
It moved quite slowly throughout, and once it really started to get interesting it was over... with a very vague, ambiguous ending at that. It didn't just feel open ended, it felt underdeveloped. The whole story did to be honest... but the idea was there.
The script was... not good. It also felt underdeveloped and slightly juvenile as well. I think that transcended to the actors performances because while neither of them were BAD, both of their performances felt stilted and just kind of weird/off. It also could be due to the fact that they both were putting on American accents, idk.
Despite its many flaws, it was still generally entertaining and I didn't hate it by any means. There was some creep factor and gnarly body horror towards the end. It landed at a 4.5 for me but I will round up as it did keep me engaged. Might recommend, but wouldn't put at the top of your cue.
