Nice to see that Kreisberg contributes to that episode's teleplay and that he has that fitting title usually associated with Batman and Superman's teamups; he's quite passionate about comic books, and if his interview with Kevin Smith is anything to go by, he'll be sure to try his utmost to make this crossover worth waiting for. :P

I also can't wait to hear Blake Neely's score and how he'll incorporate his themes for Barry and Kara in it and make them play off of one another. I'm surprised Neely even has time to score for not only this show but Flash, Arrow and Legends of Tomorrow too. At least the shows being in the hands of the same composer provides proper thematic continuity as he loves referencing character themes for heroes and villains every chance he gets.

As for how I feel about the series, so far it's been fine. The pilot worked well and even when the plot has its holes, contradictions and hiccups (notably a certain stabbing scene with Kryptonite which made me roll my eyes for lore reasons, or an episode making a complete turnaround on a previous episode's moral), the script is witty and charming most of the time, and the actors do bring their characters to life and have nice chemistry together. There are also some quite impressive shots as far as TV show cinematography goes, and I'm interested in seeing if the show can keep up its momentum or become better over time now that it's found its footing.
