I guess it's like most other endeavors. Some people love it, some don't. For me, caves and wrecks hold little interest. I dive to have fun and see cool stuff. Old derelict wrecks hold no interest unless they hold large amounts of life. Same with caves, unless there is something interesting besides what I can see at Carlsbad Caverns, I'll pass.
Add to the above, I'm not a fan of diving anywhere where a simple oops moment kills me.
