I'm not sure I've ever had a truly "bad" dive in the nearly 50 years I've submerged. The worst was probably the time my tank valve clogged unexpectedly at about 80 ft and I wasn't carrying my pony bottle... but even that dive taught me something very important!
Of course I absolutely love any dive I return from with video of some unusual behavior in a common marine critter, or some "new" species... because I get to share it with those who buy my DVDs or watch my cable TV shows.
