Rented this Korean disaster movie based on the positive review from HiDef Digest. It was pretty good. Definitely much more character driven than a Hollywood disaster movie. In fact I think they spent a bit too much time establishing the characters. I kept thinking, "Geez, just get to the tidal wave already." But I did find myself actually caring about the characters at the end. You wanted
most of them to survive.
There was quite a bit of screwball comedy in the movie, but that was part of it's charm. The CG effects were pretty good. Not quite up to Hollywood blockbuster standards, but decent enough. If you liked The Host, I think you'll like this one as well.
I'd recommend it.
