History YMMV / TheFlash2014S3E8Invasion

** Initially, it seemed that Savitar and Alchemy had no interest in protecting Earth. They could have teamed up with the heroes on a temporary basis. Savitar's absolute mastery of the Speed Force could have really helped....or so it seemed, at first. [[spoiler:It has since been revealed that Savitar is actually a time remnant of Barry Allen from the future. Now it makes sense that Savitar wouldn't help out, as the invasion was just history to him.]]

* InternetBackdraft: Many fans chaffed at the Legends getting on Barry's case for changing time, since they have their own fair share of screw ups in that area as well (Stein nearly prevented his own marriage after all). Sara in particular comes off as hypocritical by saying she has to resist the temptation to change things to save Laurel when she in fact gave into that temptation twice and was only stopped by the forceful intervention of her teammates.

* BaseBreakingCharacter: Cisco, in continuation from the last episode. Some don't agree with his {{jerkass}} behavior and how he ends up making the team question Barry as a leader because of his insistence that he tell them about the secret message[[note]]Especially considering other characters also knew and didn't tell, and it's not Barry's secret or team[[/note]], and believe he should just forgive Barry already. Others feel it is realistic for him to still be angry at Barry over Dante. Then a third camp understands Cisco being angry, but feel that doesn't justify the way he is acting.

* BrokenBase: Bringing the consequences of "Flashpoint" into the mix. Some fans are happy that Barry's dirty laundry has been aired to all his friends and allies (especially John learning he had a daughter); others are annoyed at how Barry's mistakes are being brought up all the time now, that [[{{Hypocrite}} the Legends are in no position to criticize him]] and feel like it's a distraction from moving forward.

* TheyWastedAPerfectlyGoodPlot: A fair number of heroes in all the shows don't show up in this episode (though some of them are confirmed for the other parts of the crossover).

* Narm: "Best superhero team up, ever." Thanks, Felicity...''we got that.''

** The Legends never mention that Barry's nemesis Eobard Thawne is the ArcVillain of ''Legends'' Season 2, which they should have easily figured out after finding out that they're facing a speedster and that Barry caused "Flashpoint". They don't even try to discuss with Barry about the possible identity of their speedster nemesis.

** Alternatively, given that the Dominators are mentioned to definitely exist in other universes, there was a missed opportunity to show the heroes of Earths 2 & 3 fighting off their own alien invasions.

** Savitar and Alchemy appear to have no interest in protecting Earth. They could have teamed up with the heroes on a temporary basis. Savitar'a absolute mastery of the Speed Force could have really helped.

** Team Flash never addresses that Black Siren/Earth-2 Laurel Lance is still locked up in the pipeline which should have been mentioned since they are teaming up with not only Team Arrow but also Sara Lance. Since a major theme of the episode is the bad side of keeping secrets, such a reveal would have fit in very well.
