Query: Fell asleep while watching and woke up the day after.

Thankfully I didn't sleep until the day after tomorrow. I watched - or tried to watch anyway - this big budget piece of environmentalist propaganda because it had reached the "everyone has seen it but me" kind of critical mass so that I was compelled to see it just so I can say I had.I loved the opening scene when the driller guy is standing there while a huge crack formes in an ice shelf and ends up separating him from his colleagues. This was just like an "Ice Age" movie, but with a human and his ice cores rather than a squirrel and an acorn. But it was downhill from there on. The problem wasn't that I'm a bit skeptical of the whole global warming thing (at least the part where humans did it and humans can fix it) but rather that I found the characters so dull. Spectacular effects cannot make up for boring characters, at least not for me. So, I'll be returning this movie to where I rented it from today, not the day after tomorrow.
