Watched that tonight, not bad. Troll hunter I think was better and far more scary, but this had a decent take on it... very much kind of a spin on the Godzilla Broderick movie... some campy/cheesy characters, the stupid/ignorant military, and the cliche main hero as the 'SCIENTIST' that is recruited to be knowledgeable but then nobody believes him/her lol... but it had some decent effects.
I think it lost some of it's momentum in the second half, but hey... still okay. Be prepared to watch it in subtitles if English is your only language.
I think I'd give the first 1/3 a 7 or so out of 10, and then the middle a 5'ish, and the final third a 4 or so.... maybe an average of 5.x... but that doesn't make it a bad movie by any stretch. Good creature feature...
But trollhunter is still the better film. But no reason this isn't worth a watch.
