Technically well made. Nice cinematography and effects. Especially enjoyed the action sequences underground when the infiltrators tried to take over the power station. Some well directed suspense right there! Wish there were more of that. Or just maybe that, a suspense thriller set underground with a hidden meneace. Preferable no dialog or any human interaction at all. HOWEVER. That’s not the case. Whenever characters interact with each other, or react to each other, especially when it comes to father and son, mother and daughter or even person to person, it all falls flat. Sprinkle that with a totally unlikeable male lead.
