It's a Korean produced film with an English-speaking cast? Huh.
The same director did it before. His previous film was a remake of a Korean Godzilla remake from the 60's, also with an all-english cast and completly CGI monsters. Yongarry, released stateside as Reptillian, and yeah, its really, really bad. Even as a giant monster movie fanatic, I found very little about it to like.
So it started out as...

was remade into...

which came to America as...

Yonggary was remarkable as the highest budget Korean film of all time, a title it held for several years. Up until D-Wars, no other Korean film cost even half, or even a third (or even a fourth) as much as Dragon Wars did to produce.
Even though I'm sure the film will be pants, I'm still kinda hoping it suceeds. I'd like to see a giant monster film to make bank, I'd like the Korean film industry to get a shot in the arm that the international success of this film would provide, and I'd like the non-big-studio released film to make some cash for its American distributor.
So you all go ahead and buy yourself a ticket, its for noble reasons, and heck, you might even enjoy yourself. Just go in with modest expectations.
