I have seen this in reruns in the 1980's and it wasn't too bad. Let me fill you in with more of what I remember.<br /><br />Spoilers. Valerian (I don't remember him being "Varian") had a super crystal tuning fork that could do just about anything. But he wasn't an alien. He was from Atlantis. He was healthy, wise, handsome, took his vitamins, had a clean aura, probably a vegetarian, and he never abused that aardvark in the back yard. Your basic all-around 1970's hero guy. And the tuning fork was really an amplifier that tapped into his spiritual essence to effect change.<br /><br />In the Bermuda triangle, people would get sucked in from various times throughout history. I believe it was the pilot when they ran into pirates. One of them asked if Elizabeth was still Queen of England. Clearly, they meant a previous Elizabeth. They answered yes, which only prolonged their delay in realizing they were in a time vortex.<br /><br />Roddy McDowall was a late-comer, probably to boost sagging ratings. He was from the future but I don't remember from when exactly. I think it was the 2100's.<br /><br />It turned out there were some bad guys running the island from a shiny silver cylindrical tower that looks remarkably like one of the buildings in downtown Los Angeles. They were agents working either for or with "The Source". Valerian defeated The Source, leaving the show with no direction at all. They quickly slapped together a new threat  "The Power". It some kind of artifact gun. The reruns didn't get that far in the 80's so my memory gets hit and miss at that point. I remember them beating The Power also. I think they knew the clock was running out so they were kind enough not to leave the audience hanging.<br /><br />It was a bit simplistic at times, and some of the plots were a bit too obvious, but it was good clean escapist fun. There was a family on the island with Valerian so it was easy enough to identify with someone and pretend you were there also on a wild adventure. I would watch it again if it was on at a convenient hour.
