A minor point but it got me to rewatch the first 10 min of the series. Made me realize how silly a character Finrod is - "touch the darkness once more" and "A stone can't float cause word salad."
The author basically argues that most heroes in Tolkien have heroic deaths with meaning, and he's pretty much right. You have Fingolfin wounding Morgoth over and over, Finrod saving Beren (which helps him on his journey to get the Silmaril), Fingon and Feanor die in battle with multiple Balrogs. Turgon's death is mostly offscreen but in that battle the focus is on Glorfindel killing the Balrog (and dying in the process). Gil-Galad and Elendil die battling and eventually defeating Morgoth.
And as the author states, these epic deaths are usually a cause for mourning, not revenge quests - like Fingon's death was in the "Battle of Unnumbered Tears". Finrod's death has none of that - he dies in vain chasing Sauron, mostly off screen, in the least epic way possible.
Of course, the real issue here is the innate silliness of the rights battle messing with the whole series, where for some reason they're not allowed to use the history in the Silmarillion but it's ok to make up a completely alternate version that completely conflicts with it (and leaves out major, major details like the Curse of Mandos), and include weird things like Sauron carving a map of Mordor into Finrod's flesh. I mean, it's that and the showrunners' bizarre choice to make the entire story about Galadriel. This series could have (and should have) been written without mentioning Finrod at all - he's not remotely relevant to the Second Age, having died long before the end of the first.
