It starts a little slow, but then something happens inside the tunnel.
In the beginning the movie works well, but then the rescue begins. Orders are given from people in charge, but everybody is doing the excact opposite!
I mean EVERYONE!!!
Its just completely destroying the movie, because its so annoying.
And the "hero" is way over the top.... One scene where he ends up crawling... Oh my god!
Many many people dies in the tunnel...... But who cares?
The people we follow only cares for themselves... Bringing a lot of people in great danger, and deaths, because they disobey orders.
Its just stupid and annoying because the story is good.
