It's a slow moving movie, in the jungle, looking for a downed radioactive satellite. Ending is somewhat interesting. Another movie I saw when I was a kid, was 1957's Attack Of The Crab Monsters. I thought the plot was great, but the special effects were junk. It was scary then, but boring now. Rodger Corman is a master of low budget special effects. I really enjoyed alot of his movies, and those of William Castle. Corman did make some high budget movies, with Karloff, Lorre and Jack Nicholson.
One from 1957 that wasn't done by Corman was The Giant Claw...ugh

What terrible special effects...

I've seen some movies that had good plots and story lines, however, the special effects,or acting, killed the movie. Plan 9 From Outer Space is one. They tried to remake it a few years back,but it sucked too.
