Over rated.
It has good acting & directing, ok cinematography and a cool concept and that's about it.
The concept while interesting does open up a plot hole.
The story never really seems to go anywhere. It ends too prematurely. I don't remember too much about this movie. Skip the next paragraph cos spoilers.
*Spoilers?*It starts, blah blah, random oldie gets rekt, labour, action, dude gets rekt, monster gets rekt, more monsters about to get rekt when................. THE END *Spoilers?*
It's meh. On the same level as Jurassic World or just above most Marvel movies (which are painfully average). so...... 6/10. 6 points for the positives I've listed and -4 for it's premature ending, plotholes, 2 hilarious deaths and the feeling of "that didn't really go anywhere" when you leave the theatre.
