Plantina is for sure a retelling but with sex. The plot, setup, and number of images used are just ripped out of the episode (not even re-drawn).
The CHUD story is more "inspired by" rather than "ripped from", with only a spares few screen caps from the show.
Though, to be clear, neither of those are scenes I replay (or liked that much to begin with). And while I was fine with the Plantina thing happening once, I don't want it to be the norm. I would much rather see established (main) characters do things inspired by the show, rather than re-treads of episodes from the show.
Season 5 (and 4 too) had me pretty worried. So far Season 6 has shown a strong first episode (what I was expecting from S5 but never got) and a fine second episode. Hopefully ep 3 will be enjoyable too, and, again, I hope it won't be used like the Plantina thing or the newest scene in 3.6J.
