I like it, including the A plot.
Likewise.
Garibaldi doesn't get to solve mysteries very often, and there's a lengthy list of episodes I enjoy less than Grey 17. It just has been saddled with a reputation for being a stinker (same as Infection, TKO and Grail, which I also tend to enjoy a lot more than certain other episodes).
The only part of
Grey 17 is Missing that is truly awful, is how the Zarg is killed. Steam activated bullets?
1. The bullets would not have fired.
2. The bullets would not have gone off one-after-the-other, as if being fired from a functioning gun.
3. The bullets, IF they had fired (and they wouldn't have), would have gone off almost simultaneously in a chain reaction.
------------------------------------------------------------------
Steam~~ Bullet 1 Bullet 2 Bullet 3 Bullet 4 Bullet 5 Bullet 6
------------------------------------------------------------------
Bullet 1 would have gone off, hitting Bullet 2, which then would have gone off and hit Bullet 3, etc. etc., all within a fraction of a second after Bullet 1 going off. The result would have been:
1. the pipe exploding in Garibaldi's hands, or
2. the blast wave partly progagating backwards toward the steam source, a loud bang, and five bullets tumbled/stuck in the pipe, and ~maybe~ Bullet 6 coming out at relatively slow speed,
and
3. the Zarg dying of laughter.
The only part of the whole thing that had even the slightest shred of realism was the inaccuracy of the unrifled, too large a diameter pipe.
Still, all of that amounts to only a very small portion of the episode, timewise. So, I can overlook it and enjoy 99% of the episode.
Regarding
Infection,
TKO and
Grail, I like them as well. You wouldn't have to twist my arm to get me to watch any of these four episodes (
Grey 17 is Missing makes four.) I like
Infection for David McCallum, and the technology introduced. I very much like
Grail.
TKO, well it's watchable, not much really there, but it's watchable.
The only ones you would have to twist my arm to get me to watch are:
Believers
To Live and Die in Starlight
and
the "Byron" scenes.
