Yes there was plenty of action. Kids will enjoy it immensely. Adults will need earplugs. Yes there were dogs humping other dogs and legs for teens to laugh at, but not necessary to add in. The plot was easy to follow, the actors said their lines, and it all worked, I guess, cause I left once he thrust the dagger into the robots "heart" - I sort of knew what would happen next. I just had enough of the long battles. This was not as "real" and challenging on the brain as Batman - The Dark Knight, Star Trek movies, or even I, Robot. Yes, kids have brains too, but adults, wait for your friends to rent the DVD when it comes out, then don't forget the beer - it'll be much more fun.
I wanted to get out of the house from trick-or-treaters and picked this because of the high ratings - what a blessing!! The cinematography was subpar, no big name stars, bloopers, etc. but it was the BEST movie I've seen IN MY LIFE, better than Mel Gibson's "The Passion of the Christ". I didn't know what to expect (I thought it was another action packed fireman/love story movie like Backdraft or Ladder 49) and I got more than I expected!! I recommend it to everyone reading this review.
