For a start it's way too long. Couple this with some ham acting and a dodgy plot and it's easy to start to lose focus and let your mind wander. That said the production isn't bad, some of the SFX are a iffy but for a TV movie they've not done a half bad job to be fair. Overall though it's all very implausible so that causes it to lose credibility. It's a poor mans 2012 I guess.
If you're at a loose end for 3+ hours, knock yourself out. If you like dodgy tv moves, knock yourself out. If you have the attention span on a goldfish or detest cliches and cliched storylines then you're gonna struggle.
