Going for a necro-bump on this thread, since I heard the series rapidly improves over its full run. With not a lot to watch this season overall, I figured I'd give it a look after passing it over completely the first time.

I watched the 2nd episode of Fire Force first on accident due to the way they downloaded and not paying attention. Honestly, it was a drastically better intro to the series than the 1st episode.

Deliberately watching them in that order was definitely the way to go.
