What makes it different from others?

Lack of good storyline.

It is an exhilarating, distressing, funny and profound film, with one of the more memorable film scores in years,

A film of deceptively outspoken contemporary relevance, this is cinema at its most alert, alarming and alive.

I really enjoyed Sea Hunt with Lloyd Bridges as Mike Nelson as a kid. There was no other series like it and the underwater scenes were extremely well done for it's time.Well, OK, some of the "special effects" were believable to a kid then, but obviously fairly obvious today. Such as when Mike gets tossed around by strong "killer" currents, but everything else in the scene is serene -- the plant life, his air bubbles, etc. This is somewhat like the special effects on "Rocky Jones, Space Ranger" where the actors would bounce around in their seats to simulate their ship being attached or in space trouble/turmoil for one reason or another.What I really liked was when reruns were shown in the afternoon and I was home with the flu on school days. There's so much narration by Mike that I didn't really have to sit up and watch the old Westinghouse B&W 17-inch TV in the bedroom room, on its last legs. It was like listening to the radio.Some of the episodes, though, are extremely bizarre when seen today, which is kinda fun. In one, and I guess we can have spoilers for a series that was on around 60 years ago, involved Mike and his crew summoned to either Ireland or the Scottish coast.Locals are reporting a monster, traveling a terrific speeds through the water, scaring the population and destroying the fishing industry. Mike sets up a series of underwater nets to capture the monster, but it just breaks through all of them and keeps going. Some locals have even seen it, all green.This is the dawning age of Sputnik, the first Earth orbiting satellite from the Soviet Union.Turns out this "monster" is actually some government's ocean satellite, capable of traveling at incredibly high speeds under the seas. Any green on it was just kelp or seaweed.Well, OK. Believable a half century ago as a kid.

I loved watching ''Sea Hunt '' back in the day , I was in grammar school and would get home do my homework and by 4:30 would be ready to watch ''Sea Hunt '' and Mike Nelson in his underwater adventures .I loved it ! He took to you a place not very accessible at that time , under the great blue sea . Pre ''Thunderball '' or even before Cousteau became common , there was Mike Nelson sparking the imagination of kids .I'd be willing to wager that more than a few kids developed their passion for oceanography or biology or one of the sciences from watching this show .Underwater photography also progressed , the fascination for exploration is easily stimulated thru watching this show . Watch and enjoy !!!

I grew up watching this and I thought it was the best series they had at the time, even though I must have been watching the reruns because I was born in 1957. I could never get enough of it - I had to have seen all 155 episodes, I grew up on this and was always excited to watch! The conclusion was always exciting to find out what was found and the mystery was revealed. At age 50, I watch TCM to see if it will show the old reruns of Sea Hunt to this day! It made quite an impact in my life and I always wanted to be just like Mike Nelson - he was so cool! I am an avid Movie Classic viewer and this was the best acting, next to James Cagney, the most under-rated Classic Movie actor ever.I wish they would bring Sea Hunt back so most of the young generation would understand what principals and morals are really like. Lloyd Bridges' sons truly did find what their father was really about! --A True Sea Hunt Fan

The show's echoed 'bubbling' sound effect used to put me to sleep. A very soothing show. I think I might have slept through the parts where there was danger or peril. I had also heard that some set up shots for a show on sponge divers was shot in Tarpon Springs, Florida. I would assume Lloyd Bridges never dove there. I only remember the show in reruns and although it was never edge-of-the-seat exciting we would make up our own underwater episodes in the lake at my grandmother's house... imagining the echoed bubbling sounds and narrating our adventures in our heads. I thought 'Flipper' had better undersea action. Of course, he had the advantage of being in his natural environment.
