Some previous ratings seemed extreme... before I get into some of my comments, here is my rating system
1 - This movie should never have been made. I likely didn't even finish it.
2 - I watched the whole thing... It was bad. Would never recommend to anyone.
3 - The movie was "o...k...". Generally a soft-recommend from me. I personally wouldn't watch again.
4 - Movie was good/solid. Decent to Good odds on me watching it again in the future.
5 - I need to call my friends RIGHT NOW!
So, let's start with the basics
Camera Work / Audio / Lighting - all fairly well done... ( maybe a little left to be desired on the soundtrack, but even that wasn't too bad... ) ( side note... there were a handful of shots towards the end that were extremely dark... )
Acting - I'd say surprisingly good for this genre/style. ( which also implies that the script was written fairly well )
Plot - Is not "entirely" new, but I suspect you have to be a movie buff like me to know that... Yes, I know of 2 other movies that had very similar plots off the top of my head. Either way, I would still class this as pretty unique in the sense that they attempted a merge of a brotherly "rivalry", coupled into a creature feature, etc...
SFX - Meh... They didn't do a lot. It tended to rely more on camera work and lighting rather than actually seeing any visible SFX... ( which isn't always a bad thing... bad SFX could have ruined this movie... so I think the route they chose might have been a good one... )
---------
So... I thought the movie was generally suspenseful. The jump scares weren't really all that scary, but they could be to some.
I thought the dialogue in the movie was fitting ( In fact, I can actually relate, as I barely talk to 1/2 of my cousins as they live out in Western PA, while I live in NJ... although wearing a Che G shirt is pushing it... No, I don't watch NASCAR, and no, I don't follow the Pitt Steelers... I'm more than happy to just play music in my home studio... )
Bottom line... I generally liked the movie. It left a couple questions at the end, but if you have an imagination, I suspect you can figure it out... I give it 3 stars with a soft-recommend for fans of suspense / horror. I will likely not bother watching again, but if you are bored on a rainy night or something, you can certainly do a lot worse...
