Was interesting to watch and such a good ending , couldn't imagine the fear he was going through and then the excitement when he sees the light. Really didn't like the dark haired diver (Dave) was far to rude and cold hearted towards him would hate to be anyone working with him if that's how he thinks of his crew doesn't matter what your job is if something bad is happening you treat everyone like family and do all you can to help them especially a job where he's going to slowly suffer and then again when he sees Chris is alive he's still being cold hope Chris never spoke to him again.
