FYI - I came across this site that lists various Arrow podcasts. The following four podcasts appear to be the most active and they each discussed 420...
Arrow AfterBuzz TV Aftershow (48:30) https://player.fm/series/arrow-afterbuzz-tv-aftershow-171260
-- I found this podcast to be lively. They were generally upbeat about 420. They didn't like Andy's egging Diggle on with threats to his family like a classic villain. They liked that Felicity was so good at gambling. They also brought up the idea that Felicity would be the one to fight Darhk because she brings the light, but then mentioned that Oliver is the one with the magical tattoo. They liked that O&F didn't suddenly get back together, but they fully expect them to reunite eventually. They likened Malcolm's new fake hand to Coulson's fake hand. They said that it was Diggle's turn "to carry the idiot ball". They advocated the family you choose over biological ties. They loved Lyla and her relationship with Diggle, thought they really acted like a married couple with a long history. They made fun of Alex taking "multivitamin" pills provided by his boss. The dome made them think of Convergence. They said that Thea is now separated from the team and no one knows where she is. (Hmm... but didn't Felicity put trackers on every member of Team Arrow, so they should be able to find Thea?) They agreed that Arrow should not try to be like Flash. Warning: they discussed a spoiler casting call for S5 near the end of this podcast.
Green Justice: An Arrow Podcast (01:05:00) https://player.fm/series/green-justice-an-arrow-podcast
-- This podcast was more low key. Jay and Josh spent some time recapping this episode. They thought the Genesis plot was not original. They thought the dome with its piped in music loop was like a "Disneyland for villains." They thought 420 was "good" and showed a lot of the Genesis plan, but were critical of how the plan was presented. They thought that there was too much "busywork" in intercutting the Diggle/Andy conversations and Diggle/Andy chase scenes, without sufficient "backbone". They thought the Lyla/Diggle relationship was stronger in this episode than in the past. However, one guy was critical of Lyla yelling at Diggle when he returned from being tortured by Andy. He was also critical of Lyla of putting the Rubicon in her body as the safest place to hide it, but the other guy disagreed. They were concerned for Diggle after killing his brother. They felt that Oliver has turned a corner and might now have to help Diggle. They thought that all of the decisions that all the team members have had to make lately have been tough decisions. They questioned the creation of a new character, Esrin Fortuna, rather than using an established comics character like Zatanna. One guy felt that Oliver "is not really a magic user" but is "a very street-level character" (like Hawkeye). "He's just a man with a bow and an arrow." But now he's a guy "who can channel this light inside of me". However, the other guy disagreed and loved this development because it was "something new and interesting". They thought the magic training lacked "training" and that they should've spent more time developing this over several weeks for Oliver. They thought it was interesting that "Olicity was two sides of the same coin" - light/dark, yin/yang complementing each other without necessarily being a couple. They liked the way Felicity was worked into the plot with Oliver without being part of a love story. They commented on some fan feedback: one fan said that "Laurel's death had zero impact on him" and that 420 was "one of the worst episodes" in terms of writing but that the last 10 minutes were the part he liked the most, with SA being the "bright spot" when he's in costume and repelling Darhk's magic. The podcasters disagreed that it was one of the worst episodes. One guy said that the fern was referenced again and that if they could get a new fern, that would be so great: "Season 5 would be spruced up amazingly if there was a fern". The other guy joked that his theory is that the fern is going to be the Big Bad in S5.
Quiver: The Green Arrow Podcast (01:17:00) https://player.fm/series/quiver-the-green-arrow-podcast
-- This podcast was drier and even more low key. Amanda and Mike thought the episode was alright but "kinda silly." They said there were three stories (and no flashbacks) which was "nice". They thought that 23 episodes is too much. They questioned bringing in the character of Esrin Fortuna. They said that The Flash is getting all these comics villains and characters on their show, while Arrow is now getting non-comics or made-up characters so that no one cares (unlike S1 where you got comics characters like the Huntress). They thought that every episode of Arrow just seems like this show is "lost". (I lost interest after about 20 minutes and stopped listening to this podcast.)
ArrowCast (41:28) https://player.fm/series/arrowcast
-- This podcast was difficult to listen to. These two guys mumbled a lot and were sometimes unintelligible. They started off being very critical of Felicity and how she treats Oliver. They just reminded me of two sulky schoolboys. (I stopped listening to this podcast after the first 10 minutes.)
Remember Evil Willow from Buffy and Illyira from Angel?... That's what I thought of when I first saw a pic of Killer Frost. It's all in the lipstick and tight leather outfits.
