- The joking scene at the end when Riker is cured is neat.
- Some of the scenes in Riker's dream are fun to watch again.
My Review
The problem this episode suffers from is severe lack of plot. This was due to budget problems. They didn't have enough money to do the big action packed season finale they planned for. So instead they made a clip show. What confuses me the most about this situation is why they bothered to make this episode at all. The previous episode (TNG: Peak Performance) would have made for a far better season finale.

The following are comments submitted by my readers.
- Pulaski recognizes that the microbes respond to brain endorphins. She then proceeds to jolt Riker with a machine so his brain can produce them. Yet, she worries that the stress may kill him. In "The Battle," Dr. Crusher claims that twenty-fourth century medical science has "mapped the brain." If they have, doesn't it seem reasonable that they would understand the endorphins the brain produces under different circumstances? Shouldn't they be able to manufacture these brain endorphins in a replicator and inject them in Riker? Then again, if Pulaski could make the endorphins, we would miss all there wonderful flashbacks! (Sorry, fighting to control my hatred for flashback shows)
- As Pulaski uses a machine to stimulate Riker's brain, she looks in a pair of eyepieces and presses buttons. She seems to hit the right buttons without even looking. Considering that all the control surfaces on the Enterprise are flat, that's quite a feat!
This is not a comment on this episode--what is there to say about this one, really?--but on the second season as a whole.
The second season is superior to the first, mostly because the characters started coming into their own, the seeds of coming plot arcs are sown, and the writers stopped rehashing TOS plots (with the exception of "Unnatural Selection"). On my slow process of re-watching the series for the first time in years, I was surprised to see that some of the episodes I remembered most fondly--"Contagion," "Up the Long Ladder," "The Emissary," "A Matter of Honor," "Q Who"--are all this early in the series. I distinctly remember it getting better as it went along, so I'm looking forward to the upcoming seasons.
I'm watching the series via Netflix, and the last disc I received contained the final two season 2 episodes and a smattering of special features. One of the special features was called "Memorable Missions" and consisted of the actors, producers, writers, and other behind-the-scenes types discussing their favorite episodes. I was surprised to see that the people behind the show seem to love "The Dauphin," which I consider to be among the worst episodes in existence.
Anyway, on to season 3....

Neurotransmitters released in the bloodstream can't reach the brain because of the blood-brain barrier. So this wouldn't have the same effect as stimulating the natural production of endorphin.
No one seems to remember that this episode and "peak performance" were made at the beginning of a writers strike. that why the seconds season only has 22 episode instead of the usual 26. This was a clip show that was made as filler to finish the season.
Its a clip show show, so I don't hate it! it is what it is. Im not really a fan of it, Id not even give it a rating.
