I think TNG is a lot better and find a lot of TOS difficult to watch, but I can agree that there's a good portion of TNG episode where just some stuff of little importance or interest happens (really sometimes I think TNG is the most uneven show in Star Trek, it can fluctuate wildly in quality from one episode to the next, and there are some very good TOS episodes, like the Enterprise Incident).
That doesn't detract from Jinn's opinion or deny them the right to voice their opinion. It's just my opinion to disagree with that. Free Discussion.

I'm also not saying that I think all of TOS is gold or anything, just that I find even the bad stuff very watchable and entertaining.
