definetly needs a restart. i could only imagine what they could do nowadays with effects and a solid true-to-game script. nothing specifically for children tho, has to be a hard pg-13 movie. i wouldn't mind the characters being nobodies but if they can act and perform the moves, i'm all for it. they need to just follow the game stories and everythign will be cool
i had an idea that would be incredibly awesome (i think) for a trilogy of movies filmed in sequence. they would be the stories from the first 3 games respectively. first one with older shang tsung, kano, and goro as the villains. 2nd would have shao kahn, kintaro and young shang tsung as the villains. the 3rd would be shao kahn, sheeva, sindel, and motaro. you cant just go off the villains but the first trilogy of games had some really great stories to tell from both the good guys and bad guys. from the original sub-zero being bad and the 2nd being helpful and an ally. by the end of the 3rd film liu will have defeated shao kahn (pummel him to the brink of death, possibly cripple him) and raiden would be accepted as an elder god. obviously there would be the death of johnny cage but i think that should be reserved for the beginning of the 3rd film when shao kahn invades earthrealm.
the ideas i have (past what i put above) would also be ideal for either a standalone trilogy or if they decided to make a follow-up trilogy there would be enough elements present to connect events into the 2nd trio. i'd have shang tsung petrified with magic in the end of the 2nd movie and if they never made a 2nd trio it would work , but with the 2nd trio, the middle movie of that series would have quan chi seek out shang tsung and return him to form and then they would kill shao kahn. leave his death for the villains instead of liu doing that.
if they made the 2nd trilogy the middle film would be like the empire strikes back of mortal kombat. liu would die by the hands of shang and raiden, shang and quan would all be killed (among others) by onaga (would be the end of the film leading into the last and 6th film which would follow the events of deception). i'm a big mk nerd so i know practically all there is to know and feel certain elements would be so great to see in film. there would just have to be the dedication to make this all work. as long as the scripts were well written, the effects were nothing short of great, some fantastic fights and choreography and they stick to the source material these movies would do so well i think we would get the 6 films (not gunna hold my breath tho)
