Almost 90% have no casualties, so watching is pure amazement
The thing about Hollywood explosions is the fact they aren't real, so yo don't care. Here, it's real, and you do care. They do an excellent job of finding disasters with no casulaties, but there are just enough to keep you ont he edge of your seat. Not for the squeamish, but if you like explosions and suspense, and a little shakey cam, here you go.
