Although I don't like the TOS era and TNG is in my opinion the best Star Trek series, I think Enterprise is the only non-TNG and pre-TOS series that I really like. The storyline is very fascinating just like TNG and they meet many strange creatures as they went further into space with their early warp-5 engine. Things only really got exciting when they encountered the Xindi. I was often on the edge of my seat. No TOS series like Discovery and Strange New Worlds can compete with this. Too bad it only lasted four seasons because this series deserved so much more!
