I thought all the special effects were pretty good. The plot and escape scenes stunk on ice because they weren't believable. However its a good movie to bring a chick to. I'd watch it again as long they recast Woody Harrelson's part with another crazy white guy...LOL...Everytime I see Harrelson I pray for him to finally dunk that ball like in White Men Can't Jump...Good Movie Overall...Go watch it because John Cusack needs your money...He's been casted in a few horrible roles as of lately...
