After everything we have heard from Tom Ellis (actor who plays Lucifer), I honestly did not think that we would see him in this year's crossover which made his scene even better than it already was. Moreover, this episode includes lots of thrilling and emotional scenes, e.g. Earth-90 Flash sacrificing himself, Anti-Monitor destroying the whole multiverse except for the paragons (including his own brother), Lex replacing Superman as the new paragon, etc..
All in all it is a great episode which is definetly worth watching a second time!
