I don't normally review TV or films but if I can spare someone else the wasted four hours of wading through this tripe then I will consider it worth the effort.
Where do you start? The acting is OK'ish (although bit too much breathing out through pursed lips for my liking) and the characters largely believable, but what isn't are some of their actions and the plot.
It's not so much that there are holes in the plot, there are yawning chasms. As some others suggest did the location cost cutting also extend to the filming schedule? Causing what seemed like intriguing plot lines to go nowhere and the main threads to end with mostly with no real conclusion or explanation?
If this was the set up for a second outing, you can count me out.
