It's a fascinating read, if a little flawed in places.
Agreed. (Thanks for posting the rest, by the way. I'd only previously seen the first two parts.)
It's one guy's perspective, so it has to be taken with a grain of salt, but it chimes with a lot of what I have surmised about the TNG-era from watching the shows.
He's right about DS9 being possibly too complex and too intensely self-involved, but he's also right that that's part of what makes it a great show and a lasting achievement that will hold up over time: it is "a real place, a truthful place."
A lot of what he says about Voyager strikes me as pretty accurate as well. Basically there was simply no creative energy there, and a great premise was wasted.
