Voyager had so many terrible plot devices. The time that they were able to punch a hole in the event horizon of a black hole, and the then escape through it, still sticks in my mind 25+ years later.
Yes it was a holy staff. It was the TZ episode The Howling Man. I like the episode. Maybe because John Carradine plays the monk with his usual scene chewery.
Damn. I generally thought Star Trek TNG was pretty good for its time, but there was one episode that was excruciatingly bad.
Alas, to paraphrase Julie Brown, “It was so stupid, you know what it was 'bout? Well, I forgot what it was about, 'cause it was so stupid!”
I agree with @Scoobysnax, though - Voyager had more than its share of astonishingly dumb episodes.
I still remember the episode of Space: 1999 where they flew into and out of a black hole and maybe met God.
There was a Gerry Anderson pilot called Into Infinity that was basically Lost in Space meets Space: 1999, and they did the same thing but emerged on the other side of the Universe.
“We needn’t worry about flying into a black hole. Nobody’s done it before, so we don’t know what’s going to happen.”
Yeah, right. 
The first episode of the Twilight Zone is this guy walking around a town that’s completely abandoned. He has no idea how he got there or why there isn’t anyone in the town. He eventually goes crazy and we find out he’s an astronaut that’s training for traveling around the moon. He’ll lose contact with Earth when he’s on the far side, so this simulation is to prepare him for that.
Of course, the situations aren’t remotely the same. One is a completely bizarre experience where you have no idea what’s going on or happening to you, and the other is “hey Jim, we’ll see you in two hours, keep an eye on the instrument panel.”
Conversely, there’s the ST:TNG one (“Genesis”) where Dr Bev has a little oopsie and unleashes a devolution virus on the ship. Troi becomes a frog person. Picard starts turning into a lemur. Data’s cat Spot devolves into an iguana. It all gets laughed off at the end despite several crew members dying.
IIRC, you’ve got the details a little mixed up: he wasn’t walking around in a deserted town that’s filled with tantalizing hints that people had just been there; that wasn’t the plan for prepping him for the mission. It’s that, while being prepped for the mission, he went crazy and so then started hallucinating that he was, y’know, wandering through some town.

Without disturbing a hair on his Vulcan head.
AFAIK, they never explained how there could even be a human/Vulcan hybrid. So that throws everything Spock related into dispute. I demand a certain level of plausibility in my made for tv science fiction.
FWIW they did explain it in the novel Spock’s World, though that came out 20 years later. Basically lots of genetic engineering between Sarek & Amanda.
I second this!
It did have a pretty dramatic moment when the drug addled Walt almost confessed to letting Jane die. Other than that it was comedic. I’ll argue that one of the falls he took trying to get the fly should have at least bruised a few ribs.
I’ll see you and raise you Saddlesore Galactica.
He didn’t just happen to go crazy; the hallucination was induced by being confined for days in an isolation box. They actually did tests like this in real life.
I had to look it up. Your synopsis sucks 
Even before that, Roddenberry touched on it in The Making of Star Trek (1968):
Conception and pregnancy when properly planned and controlled by technicians of the highly advanced Vulcan school of medicine can be brought to full term. (P. 299)
In other words, Spock was something of a test-tube baby.
The latest episode of Ted Lasso was a low point in the series.
Do you remember that episode of Happy Days where the Fonz jumps the shark?
Polluted water was the in-universe “explanation” of the acceleration. Yes, Gene used the WWW idea when he wrote the episode for ST:TOS.
Probably the stupidest episode of BtVS was “Beer Bad.” That the episode was written by people who should know better makes it all the worse.
