Where to begin?

1. Dumb, far-fetched story line about a shark following people over great distances (was much of it a dream?)
2. Contrived conversation between actors playing marine biologists--they try and fail to convince us that actually they talk this way to each other all the time
3. A lead lady who really should have stayed just a supporting player (shows don't always wish for more of what you like)
4. Annoying child actor
5. The central character is cured from terrible trauma of child-loss in as much time as it takes to get a haircut (why did they not simply have her see a psychiatrist?) thus killing any attempt to present her problem even three quarters realistically
6. Criminal under-use of ultra-great lady (Karen Young)
