Why did you ignore The Other Waldo Pepper’s post, which did have a plausible explanation?
It’s called “Writing one’s self into a corner.”
See BSG.
As an aside, in Enterprise, he acted as though he had jumped into a Starship Captain and didn’t know what to do.
Because I didn’t notice the post. But to answer it, since you feel I must…
What you’re saying is that at the opening of the final episode they should have retconned every episode from the first on? Really, then you’re making a time loop/paradox. If you check out the “Worst movie endings thread” you’ll see people calling “12 Monkeys” a terrible ending because it’s a boring predictable time loop.
“Let’s see. I am going to skip saving MLK from an assassination and instead save a random housewife in 1971 who was killed by her abusive husband. And after that I’m going to program in a couple hundred other fairly minor events that involved bad things to random nobodies. Sure, I could help with some big things, but, eh.”

I didn’t say it was good. Just plausible. 
Oooh, Alias was another one that completely shifted gears the last season and pissed everything down the toilet. Between Alias and Lost, I will never again trust JJ Abrams to be able to deliver a satisfying ending.
Sopranos. Let’s put on a mediocre ending and the humanoids will think we are brilliant.
Star Trek TNG. What was it again? Haven’t seen it since it aired and don’t care to.
“Las Vegas” was disappointing because there were a lot of loose threads left.
Before “MASH” a lot of shows didn’t have “big Endings”. There were exceptions like “The Fugitive” and “Mary Tyler Moore” but many just faded away.
Pepper Mill was SOOOO disappointed that, when the transporter finally worked in the first episode and beamed Scott Bakula on board, that he didn’t say “Oh, boy!”
All Good Things. Not bad, given how much of TNG consisted of, “Of my goodness, we musn’t hurt anyone!”
Didn’t it basically show that the Enterprise was responsible for the creation of life on Earth somehow?

They prevented the evolution of some blue green algae goop that was the basis for life on Earth. Q ridiculed Jean-Luc through time and space until he prevented the prevention.
So, apart from one double-negative I was completely correct?

IIRC it showed that the Enterprise unknowingly caused an anomaly that would have prevented the creation of life on Earth. However, it turned out that the anomaly was a kind of puzzle created by Q to “test” humanity, humanity being represented by Picard and his crew.
I actually thought the TNG series finale was quite a bit better than the first TNG movie, Star Trek: Generations, which killed Kirk and destroyed the Enterprise-D.
I listened to Baltar and now my pee-pee burns.
The Enterprise (being tricked by Q) created some sort of reverse-time anomoly that got bigger as you went back in time. As it stood, it would’ve prevented the beginning of life on Earth. So they had to solve the puzzle and eliminate the anomoly so life wasn’t prevented from starting. So the Enterprise wasn’t responsible for creating life on Earth, but rather, they had to restore the original timeline before they fucked it up in a way that would’ve prevented life from forming on Earth.
That sounds silly, I barely remember the details. It was mostly Q fucking with them, as always.
I recall that three Enterprises from three time periods caused the problem, and Q goaded Picard into being able to prevent it.
All Good Things… was redeemed by Riker blasting through the Klingons from below in the only recorded instance of a TNG officer thinking 3 dimensionally.
That’s like saying a particular episode of “Lost” was redeemed because it was the one time Kate didn’t get held hostage to force the rest of the crew to put their guns down…!

That was pretty cool, Enterprise passing through Klingon debris.
I agree with BSG and Lost, but more than those it’s the non-endings of a dozen cancelled shows with potential that bother me. It annoys me when an interesting series ends on a season finale cliffhanger, and you know you’re never going to see what happens next.
