The WORST one was from TNG's "Q-Who":No, no, no. Perfect example is "Where Silence Has Lease". That conference room scene is appalling. "There's an alien out there that wants to kill us...what do we do? LET'S TALK ABOUT IT FOR 20 MINUTES!".
Kirk would have had that thing handled in half the time.

^^^(The tractor beam is green)
PICARD: Report, Lieutenant.
WORF: The beam is draining our shields.
RIKER: If they pull down our shields, we're helpless.
PICARD: Warp eight, any heading. Engage.
WESLEY: Captain, the beam is holding us here.
RIKER: Increase power!
WORF: Shields weakening.
DATA: Shields will be down in eighteen seconds.
PICARD: Locate the exact source of the tractor beam. Lock on phasers.
WORF: Phasers locked on target.
PICARD: Fire.
WORF: They still have us.
DATA: Shields are down, sir.
(A circular cut is made in the hull, and a section of several decks is pulled out)
WORF: A type of laser beam is slicing into the saucer section.
RIKER: Carving us up like a roast.
PICARD: With whatever force necessary, terminate that beam. Fire when ready.
(They blast a big hole through an edge of the cube)
PICARD: Again, Mister Worf.
(Two more holes are blown in the scaffolding)
DATA: Tractor beam is released, sir. Force field is maintaining our hull integrity.
RIKER: Damage report?
WORF: Coming in, sir. Sections twenty seven, twenty eight, twenty nine on decks four, five and six destroyed.
PICARD: Casualties?
WORF: Eighteen were in those sections and are missing.
PICARD: What is the condition of the alien ship?
WORF: They have sustained damage to twenty percent of their vessel. Life support minimal.
PICARD: Conference.

GUINAN: They're called the Borg. Protect yourself, Captain, or they'll destroy you.
And what's the result of this conference, Riker suggests since the Borg paid them a visit, he should take an away team over tpo the Cube and do the same. And even more hilarious is, they are surprised when Riker says:
RIKER [OC]: The Borg seem to be using their combined power to repair the ship.
IDK what the writers were thinking - What competent Captain would call a conference in the middle of a battle; and then decide it's a good idea to send his First, Second, and Third officers onto a hostile ship that's 80% operational still? It have to wonder if the writer's room conversation was "Hey we've gone 5 minutes without a conference room scene...."

Had this been TOS - the episode would have been over once the Borg damaged Kirk's ship and killed 18 of his crew...Kirk wouldn't call a conference, he'd do what a comportment Captain should do - Continue firing until the ship was 100% destroyed or disabled then scan the wreckage for intel/info. What Kirk would do, is call a conference in the middle of a fight.
