I thought it was great!

I really don't understand what's with all the hate. I was kind of skeptical should I watch it or not , seeing people on IMDB hate it but I had nothing else to watch so I did this one.
Overall I gave it 8/10 , pretty good action movie , with a nice twist that I would never ever think would happen , really surprised me.
I saw some people commenting the age of the mother , but did those people even watch the damn movie? And low budget? LOL okay , why?
IMDB has become infected with these kids or whatever where the rating system has become completely useless.
