the worst adaptation has to be : street fighter (1994)...damn how good that movie could have been had it been done the right way, it was an amazing cast, raul julia as bizon is just a perfectly casted actor for a great villain, shame how this generic film turned out
I would rather watch Street Fighter the 1994 film than 2009's Street Fighter: Legend of Chun Li. Now that was horrible!
Good movies, I still think the gold standard is Mortal Kombat. And now this is a web-series, but they made a 2.5 hour movie of Street Fighter: Assassin's Fist that is really awesome!
