To a true Mortal Kombat Fan, this movie is amazing as it includes a load of characters from the computer games such as Jade, Sindel, Mileena, Rain, Baraka, Sheeva, Motaro, Shao Kahn, Jax, Ermac and Cyrax who weren't in the first movie. There are loads of special moves incorporated in the movie, taken from the game, which makes it great. The storyline is abit simple, some scenes were repeated (Rains/Baraka death) and there is some historical inaccuracy, thus decreasing the popularity of the game. But if you like mortal kombat the game, film and TV shows you will find this sequel fits in perfectly with the collection.
P.S. Watch out for the 3rd Mortal Kombat Movie which is up and coming. It will follow the plot from Mortal Kombat Deadly Alliance. Most of the characters will be played by the original characters in the first movie. This movie has great expectations!
