5) Musical Meet-Ups
The four-way crossover isn’t the only crossover that will occur this season. Just like last season, The Flash and Supergirl will also crossover, with Kara visiting Central City. However, there’s one extra twist – these crossovers will comprise a two-part musical special.
This is something that a certain subset of fans have been calling for for a while, given that the Arrowverse contains so many cast members who have proved their musical capabilities in previous roles – not least former Glee stars Grant Gustin and Melissa Benoist themselves.
Even if you’re not part of that subset, this is a great sign for the future as it means the writers are stretching their imaginations and trying out new ideas. The last thing that should happen now is for the shows to find a groove and stick with it. They need to keep trying out new things to keep the universe fresh.
Plus, a rumour going around states that the episode will be directed by The Avengers’ Joss Whedon, which should get any superhero fan, musical lover or not, excited.
