I just finished watching this.
I would say it's a strong 6/10, mainly for the fight scenes.
I'll echo what others have said regarding it feeling rushed at times, the editing felt on the choppy side and for a movie that tries very hard to have a plot it was hit and miss. Don't get me wrong, I absolutely enjoyed the movie -- but it could have been a lot more. It was visceral at times while at others it seemed afraid to go that extra step. I found myself wanting to watch a movie based around Scorpion more than the story we were given. When it's good it's very good, when it's "bad" it's average and inconsistent. There were unnecessarily lengthy periods where not a lot happened, I'd compare it to earlier Monsterverse movies that tried to focus too much on the 'human element' when ultimately all people wanted to see were the badass fights.
I do agree with the choice for Johnny Cage to be absent, there were some very strong personalities in the movie, Kano especially, which would have clashed with such a character. I think it's very obvious that Johnny Cage will be the focus on the next movie should we get one.
Overall I enjoyed it and I would recommend seeing it, but I'm not sure if I'd recommend paying the current asking prices unless you're a fan of the franchise.
