Girls Night Out allows the women of The Flash to step into the spotlight, have some fun, and even battle the week's Big Bad, all without batting an eye.
It would have been prudent if the writers addressed the trauma Iris experienced at the hands of Caitlin's Killer Frost instead of attempting to gloss over it.
What elevates this episode above just being a fun change of pace is that the show uses the opportunity to address something it's struggled with for most its run: the relationships between its female characters.
Was [this] episode perfect? No. But it at least had the ladies interacting for more than a minute and teaming up together to take down a new villain of the week.
Overall the episode was pretty fun and it featured a lot of great moments between the women of the show and some comedic hijinks from Barry's Bachelor party.
