Er???
Ok, so this movie had a few of those parts that make you go "Huh??" (Quarter eating, blood drain, John Goodman) but there are parts that just don't make sense.
Like...since when can manholes with HOLES in them hold natural gas?
Since when do small bumps/pot holes make a whole truck explode? (I realize it was the manhole, but a truck still would not explode from this)
If the sewers were full of natural gas, wouldn't a truck exploding over the sewers ignite the gas?
Since when do police forces have a ready supply of flame throwers?
Just a few things that kinda threw me off.
