Save your money - seriously.
Ok, I'm not going to go into the minutiae of why this was such a train wreck but I'll just highlight some of the major issues that really killed this movie for me.
The Bad -
1. Script was probably 30 mins longer than it needed to be, laboring pointless issues that gave nothing to the film.
2. Actors, some of them (not all) looked like this was their first time in front of the camera. They were so wooden it was painful to watch.
3. If you can't do CGI well or don't have the budget for it, leave it alone. This looked like it was done on a Commodore 64. Learn from other films (Blair Witch, Cloverfield, Cloverfield Lane etc. etc.) We don't need to see a monster, build suspense, tease but don't make it look like a throw back from Jason and the Argonauts.
4. Overall look and feel of this was that it was made by a bunch of Uni students on their summer break.
The Good
1. The Dog. Now there's a dog that can act. I just hope being cast in this film doesn't kill his career.
2. This idea, the whole premise of the myth could have been done really well. It did have plenty of potential, but sadly ....
Anyway, I know there're are folks out there that might enjoy this and that's fine but honestly the 5 of us certainly didn't.
I guess its like wine, just because you don't like it doesn't mean its bad. Some people will drink anything
