What just happened?
The last time I did a full rewatch the only thing I remember is I fell asleep during this episode, in the middle of the day, while drinking coffee, so this time I was determined to stay awake and pay attention.
And I managed it, but... it's even worse when you actually pay attention to what is going on.
Alien invasion, universal annihilation, time travel, parallel worlds, alternate universes, evil doppelgangers... the plot is essentially a loosely stringed together sequence of science fiction catchphrases while they beam down, walk around, beam up, talk a bit, beam down, walk some more, beam up, talk a bit some more, beam down...
Their idea of spicing things up with action is consistent of disco wrestling and repeated falling of a cliff in a manner about as convincing as a Monty Python sketch.
Everyone acts like an idiot, nobody trust Lazarus at any single point, he's recognized as a liar, he declares intent to steal the dilithium crystals yet nobody thinks to put him in the brig, or at least have a security guard follow him, and the one time a security guard is there, McCoy says he shouldn't be there(?) because Lazarus isn't going anywhere(??), and then they just leave him alone(???) and he walks away again(????). What the actual what?
The final confrontation is the stupidest thing ever...
In the clunkiest bit of exposition in an episode full of crappy exposition the bad Lazarus, who's really the good Lazarus(a wonderful twist! good sci fi needs a twist!) explains the hurt Lazarus, who's really the mad Lazarus needs the dilithium and his ship to open a passage to cross over to another universe where he somehow already was before and managed to destroy an entire planet except the one guy he really wanted to destroy and instead of just shooting the other Lazarus what he actually wants to do is grab him which would destroy two universes, unless they touch in the corridor in which case it's fine, but then you have to destroy one ship which will destroy both ships and close the entrances to the corridor.
Because apparently the corridor isn't yet open, all the previous blinking out is never really properly explained, nor why the Lazaruses sometimes switch places, sometimes they don't, sometimes everyone feels the blinking, sometimes it's just Lazarus...
Anyway the gist of it is, the two Lazaruses can't touch.
Fine.
How about one of the security officers or Spock shoot him with a phaser, take away the crystals, destroy the ship that's necessary to open the passage thereby ending the threat and just take the crazy fella to the mental institution?
Nope, bit of Kirk wrestle and eternal torment for both Lazaruses, that makes total sense!
Because it's poignant, and real Sci Fi needs to have a poignant ending!
(Sidenote: if you look at the background during that final fight, one of the security guard extras is grinning at just how silly all of this is).
Basically the only thing missing for this episode to make perfect sense would be if they beamed down at some point to play american football in tuxedos.
As for positives... it felt like a brand new episode because I've managed to forget most of it.
I also liked lieutenant Masters.
That's pretty much it.
