Supergirl Season 2

[Tenzhi]

I assumed the Kryptonian thing was some vampire cult I'd never heard of and Not Doomsday...

But I'm more interested in what happened to Mon-el.  Was that a Boomtube?

[Golden Girl]

It's an opening to the Phantom Zone, if they're following the major points of his comic storyline, which they seem to be - a Boomtube is usually more yellow colored with a kind of grid pattern to it.

Let's hope it is the Phantom Zone as that should lead us to the Legion.

[Golden Girl]

I'd love to see the Legion brought in too - they've shown the flight ring now more than once, which seems unnecessary if it's just meant as an easter egg - the only barrier might be budget wise when it comes to showing 1,000 years in the future.

[saipaman]

Is there a requirement to even show the future?

Mon-El and company could just appear in a time bubble and talk about the future.

[Golden Girl]

I feel that it'd have more dramatic impact to have Kara visit the future rather than Mon-El just reappearing after a few episodes and explaining that he'd been gone for 1,000 years.
It might be possible to do it within a TV show budget if they had it like the Black Mercy episode in season 1, where a lot of it was spent on Krypton, but indoors, with only a few views out of the windows and a couple of establishing shots - which is also how I think they could do Kandor - although in both cases an indoor setting heavily limits any kind of flying action.

[MyriVerse]

Having Kara go anywhere really ruins the show for the other characters. Notice that even her crossover episodes have her being home in them. The center of action for Supergirl is National City and its surroundings. The future has nothing of import for this show. The only significant dramatic impact would be Mon-El showing back up in the present with some LSH friends and a baddie or three.

I feel that it'd have more dramatic impact to have Kara visit the future rather than Mon-El just reappearing after a few episodes and explaining that he'd been gone for 1,000 years.

I'd like that a lot also -- poignant lovers separated in time would be much better -- and we did get the Legion foreshadowed already I believe.  As for cost, just put the future in space most of the time -- no more expensive than the Daxams.

Oh and on Doomsday:  Original Doomsday wasn't so much a character as a (rather stupid) plot device.   To make sense, he needs enough of a travel power that you can't beat him by just getting him off the ground he needs to walk on -- as originally written, throw him into space and only the power of a bad writer's intervention could save him -- any GL takes him out in 30 seconds with no fuss.

Regarding Alex and Maggie... I've found that on all these shows, they're really much better if you fast forward through any scene where two characters are alone having a deeply emotional talk -- and you miss absolutely nothing.  I don't feel deprived from not actually having watched any scene with Iris alone with Barry or her Dad on the Flash this season after the first couple episodes.  Alex and Maggie seem to have nothing to do with the story aside from being Alex and Maggie.  Couple, got it, don't really need anything else.
