Revealing mistake: During the Scorpion vs Sub-Zero fight, after the ice-bridge collapses, when Sub-Zero jumps down to the lower level of the stone bridge to face his foe, you can see the floor beneath him ungulate as he lands, revealing there's a pad beneath the snow.
TedStixonRevealing mistake: Cyras appears, who launches two spherical bombs that attach to the walls and explode. Watch very closely. There is a low angle shot pointed towards a doorway right after they explode, and you can see the set wall visible shake for a brief instant from the pyrotechnics. It can be hard to catch, but once you see it, it's very obvious.
TedStixonRevealing mistake: During the Scorpion VS Sub-Zero fight, at one point, Scorpion kicks Sub-Zero and he almost falls into a lava pit, falling and wedging himself next to a stone pillar. (It's the bit where Liu has to jump across to save him.) When he hits the stone pillar, it wobbles like it's made of styrofoam, revealing it's not really stone.

Answer: Mortal Kombat 2 was given a budget around the same as the first one probably indicating that New Line (makers of the film) were not convinced the film would not be as much an success as the original was. The buget of 30 million is not too high of a risk for a major film studio. The original was more built on the novelty of the video game and the interest of how it would translate to the screen so a sequel was always going to be tough. While it's hard to find out why the quality was unimpressive, this can just be more from different film crews from the first or just tougher f/x to try and create for the film in the time available. Take The Mummy Returns for example. The Scorpion King near the end looked far too computer generated. This was despite a massive budget and impressive CGI for both films.
