I would give this a 75% rating if I could. Since I admire the effort that the film makers made in creating this film I'm gonna round up for this one.
I guess I have to start with the fact that there is not a lot of screen time devoted to the creatures in Monsters.
Notice I said creatures.
I don't believe the creatures are the real monsters in this film. That said, yes, this is a film with a political statement at its heart.
Which is fine with me.
Acting is fine. Really enjoyed Whitney Able. She should be moving on to bigger things based on what I saw here. (She is also very attractive...grrr!)Scoot McNairy plays the male lead and does a good, if not stand out job.
Good tension with top notch FX...all the more startling because it was done on a home computer using over-the-counter software. Understand that almost everything you see in the background is CGI. The tanks, ruble, planes, road signs and, of course, the creatures.
Speaking of the creatures, I thought they looked great. Kind of like an octopus crossed with a horse....almost Lovecraftian.
Is it anti-climatic? Yeah, a little. But I enjoyed the point it made in the ending.
See it for what it is not for what it isn't.
