the first Terminator was a huge ripoff of (I believe) a Twilight Zone or Outer Limits episode...
It borrowed and expanded on ideas found in two different episodes of The Outer Limits. I've seen both episodes, and can say definitively that Terminator is not a huge rip off of either of them.
Cameron has a long history of being accused of ripping people off. His TV series, Dark Angel is often considered a rip off of a series of James Patterson books.
