First Movie was about as good as it gets.
The second movie was entertaining but nowhere near as good in my opinion.
What the second movie did do though was answer allot of questions from the first, give a good back story on the characters which wasn't done in the first and most definitely leave a wide open door for an outstanding 3rd movie.
With the way they left the door open, the success of the first movie and all the question answering and character building they did in the second, they have a great open platform to make a quality action flick in the third.
They wont have to spend any time answering questions or closing plot lines. They can just make a good action flick filled with gratuitous violence for us to enjoy.
Cant wait.
