This was a fun little series. Even though it's 51 years old, it felt very fresh. I found it to be quite a refreshing smart take on time-travel. The story was well written and coherent. It was funny though seeing the *futuristic* computers of 1990 (which was 20 years in the future for the show) knowing that computers and electronics were already way beyond what they showed. How I rate: 1-3 ❤ = seriously! don't waste your time 4-6 ❤ = you may or may not enjoy this 7-8 ❤ = I expect you will like this too 9-10 ❤ = movies and TV shows I really love!
