They added new characters when there's already a load of originals.
They often didn't do finishing moves for major characters.
Scorpian literally came back from hell to fight sub zero but didn't have his powers/moves.. no teleporting etc he blew fire out of his mouth instead and did some choreographic dance/fist fighting/sword fighting with the new guy.
Overall they could have made the movie great by just sticking to the original charecters with their original moves, and the new character is not cool at all. His unrememberale black panther knock off.
