TNG was best in the middle; seasons 3-6ish. 7 is an... interesting watch so far; I really get the feeling they were running out of ideas at this point.

I will never be able to say anything bad about TOS because I grew up on TOS and the TOS films and, as I am often fond of saying, I feel that they sort of raised me, in a way. The crew of the Enterprise will always feel like family to me.
