This was a solid disaster film in every way, with surprisingly good special effects for something not made in Hollywood. We watched the Asian film Tidal Wave not long ago. It was fun, with very commendable effects too, but excessively unrealistic in far too many ways. It was still enjoyable, but a lot of Tidal Wave was so goofy we wondered if the film was actually a comedy, rather than a disaster epic.
The Wave is pure disaster fiction, based on something that supposedly did, and one day may again, happen. Action junkies who get bored all too easily with any semblance of character development - you know the type, who apparently doesn't think deeply enough to get that it's the emotional connection to characters that heightens our sense of suspense - might get restless in the beginning, despite the gorgeous locale. But the filmmakers drive this one home without any overt silliness or burdening the viewer with the need to unreasonably suspend disbelief. I'm still wondering what happened to the cruise ship from the movies theatrical poster (no ship that size in this film). But, aside from a rather trite resuscitation scene (spoiler: you know where they try to revive someone, give up and then someone frantically starts at it again before the person finally come to - seen that way WAY too many times already for it to be effective), there's little to criticize from my perspective.
The BD includes the original Norwegian language track with optional English subtitles. It also comes with a very nice lenticular slipcover for those who pick it up before the first pressing sells out.
