I had no idea there were only 3 seasons! As a kid, you thought the series went on and on. Great story writing, vivid colors, and imagination for back in the 1960's. If you are a die hard Trekkie fan---this buy won't disappoint you!
I was a little afraid of buying this remastered version of star trek and having strange space scenes that would look too sophisticated compared to the original ones. But the result is good, and don't distroy the old memories I have from the original series. Recommended.
