20 or so years later I'm in the cinema watching the new Mortal Kombat movie and to be honest, I really enjoyed it! As long as you know what you're going to watch and manage your expectations, you'll be satisfied. The fight scenes were really good, I believe the characters were presented well and they stayed true to what people expect from the games, and it was an overall fun experience.
Sonic was the same; if you manage your expectations on what kind of movie it is and who they're targeting, you can still have a good time (specially since they fixed how Sonic looked from the first trailer... that was horrible). The Detective Pikachu game was also a great movie to watch just for fun.
So is it safe to assume that nowadays people are able to make good video game movies? I'm looking forward to the Borderlands movie (my favorite game franchise) and I pray to the movie and video game gods that it doesn't suck lol
