Let's be honest here. All the of others are all the same show with different characters, minus the later years of Enterprise. They all follow the same formula just about every episode. The Enterprise visits a planet with aliens that look just like humans but with clay bumps on their heads. Some weird spacial entity thingy threatens to destroy the ship. They techobable thier way out of it and have a good laugh. The end. I'd much rather see Sisko and Kira kill bad guys. TOS gets a pass because it invented the formula.
Have you actually watched TOS?
