Okay, so I rented this movie because of Paul Gross and Callum Keith Rennie (of whom I knew from "Due South"), but let me tell you, H2O is NOT a light movie. It's a heavy political thriller that is not as predictable as what you may think. Even if you're not into politics, it doesn't matter! It will still interest you, nonetheless, with its unraveling plot and beautiful cinematography. I don't want to give too much away, but although politics plays a large part, there are a lot of other hidden issues such as moral implications. I expected a mediocre movie, but to my benefit, was greatly surprised and responsive. I'm not much for buying any entertainment unless it really hits me (I own like what? 5 movies?), and since I didn't get the full jist of it the first time around (my fault, I had too much on my mind), I'm going to buy it for my collection and to enjoy it once again!
