Did You Know?


Earth-X's Snart makes an overture towards Sara, a callback to their implied relationship in Season 1, thereby also suggesting that he, like Sara, is bisexual. See more »


Mr. Terrific points out that Overgirl has absorbed so much radiation that she is about to reach the Chandrasekhar Limit and go supernova. The Chandrasekhar Limit only applies when an white dwarf star reaches a mass approximately 1.4x our sun. Even if it was applicable to Overgirl, the resulting supernova explosion would have completely destroyed the earth, given the close proximity, not to mention most of the rest of the inner solar system.

Rene Ramirez: About time.
Mick Rory: I knew I could count on you, Pretty. Did you bring beers?
Rene Ramirez: Better yet, an army.
Nate Heywood: Who needs an army when you got Legends?

This review goes for all 4 crossover parts
15 September 2018 | by Eye_MD_BSee all my reviews

What I liked was the creative idea of crossovers, even though it is not new, but I never had seen one to this extend. I also did like the tremendous work which must have been done on consistency (apart from minor flaws).

But what I didn't like was that plots to some shows were put into others, so that viewers are forced to watch all four crisis on earth in order to continue their own series. But keeping the plots in the own series is also a weakness, because we know which characters musn't die until their stuff is done.

What I can't stand anymore are those tons of Nazi-episodesin nearly each series since ... well, the Nazis. How much longer do Hollywood-producers want to keep up sucking on that theme after more than half a century?

What I personally find a bit too much - especially in a family-rated series are the many and visually extreme flashing (no pun intended) fight sequences which I think are bad for the eyes of kids and also for the story-line, because quite a bit of that time could be used for a more profound story-telling.

And what got on my nerves was the constant and predictable agenda of making love in any ways possible, and marriage - in my eyes a weird contradiction - so is it now about having all fun or about being a conforming smallest cell of society in form of a couple? (Both concepts btw seem just fishing on viewer's possible likings).

Talking likings - I can't shake the impression that this entire crossover was a mere "fishing for rating"-endeavour: * Throw in as many superheroes as possible so that each fanbase is covered, * Please the LGBT as well as the good conservative citizens with emotional drama. * Please the need for a simplistic good-vs-bad-axis by throwing in a by now total outdated enemy.

All of that, but after 4 episodes my feeling was: "What did I actually take away of this entire day of watching this crossover?"

If I was a producer of a teenager-show I would feel compelled to deem it my responsibility at least attempt to bring some value to them, so I am saddened that them with all their money miss out on such great opportunities to inspire their viewers.
