Supergirl lost me a long time ago. It just wasn't the show for me. But I tuned in to this episode specifically because Grant Gustin was appearing as The Flash. The show's campy tone or cheesy and awkward dialogue hasn't changed at all, but I had some fun with this episode. If for anything else, hopefully this opens the door for more crossovers for any networks to comply with each other for a one-off.
If for anything else, this episode established the undeniable chemistry between Grant Gustin and Melissa Benoist. Benoist has always been the highlight of the show for me, and putting her alongside Gustin proved to be a great choice. There isn't a whole lot of explanation for why Barry Allen ends up in National City, except that he was just "working on his speed and ended up going through dimensions". But if you can get past that lack of explanation, I don't see how you couldn't have fun watching these two heroes fight together side by side.
The initial scene of Flash meeting "team Supergirl" with Wyn geeking out like Cisco on Flash or Kara in absolute awe of Barry's powers was funny, even if the jealousy of James got in the way. I don't really care for any of the side arcs currently going on including Lucy Lane apparently being in charge at the DEO? Or Wyn's girlfriend turned super-villain, Banshee? Or yet another superhero show doing the "city against hero" storyline. Or really anything involving Cat Grant, but I did enjoy every bit of the dynamic between Supergirl and Flash.
Overall, it was a basic superhero arc with the hero having to convince the city he/she isn't all that bad (wow that was a cheesy ending in the park), but hey Flash and Supergirl teamed up and that was cool. I'm not sure how many more times, if ever, we'll see these two together again, but I enjoyed my time.
