tons of characters died this season and lots of shit is missing which makes the lore of the show almost incomprehensible. All I assume for budgetary reasons
- portal stones/traveling with em was completely removed from the show, missing the entire alternate realities and "the flickers" that were really great lore building
- matt doesn't go to the wastes, he enters the aelfinn gateway in panarch. elaida also entered it 10 years earlier and comes out changed
- elayne and aviendha are scissor lesbians, neither has expressed a love interest in rand yet, they just wanna dyke it out. min is like 20 years older than rand and fugly
- there are only 8 forsaken in the show, although ishamael and sammael have been killed off already
- no slayer, no fades at all in season 3, the battle of 2 rivers was a single night and pretty weak, perrin just lets padan fain go (lol)
- verin never goes to 2 rivers, its alanna instead who has 2 gay warders
- siuan dies in the s3 finale as said above
- loial might be dead, he vanishes in The Ways in episode 7
- Portal Stones (I assume you mean the sculpted stone leaves on the archways) weren't removed from the show, we see Loial use them a few times, but the show does not mention the possibility of sealing a waygate permanently so yes it was dumb that he sacrificed himself to destroy a waygate's exit in the Ways, but at the same time I understand the reason why Loial had to go, because Perrin's story is done for now and Loial really does nothing for most of the books, at least nothing really visible until the Last Battle and even there he's really a footnote in the grand scheme of things.
- I really liked the encounter Mat had with an Eelfin, it felt suitably creepy and otherwordly, no complaints really, but I wish they had focused a bit more on the polearm he was hanged from, hope they don't forget about it later.
- Elayne and Aviendha don't really feel like they're going to be with Rand at all in the series, even if they weren't lesbians to begin with. Aviendha has a love/hate relationship with Rand at first in the books, but in the series it mostly looks like disdain or just lack of interest. Elayne has barely even met Rand in the series, same with Min. Honestly I feel the show is trying to salvage a Rand/Egwene thing, which is a possibility if you consider this adaptation to be another turn of the Wheel I guess.
- Ishamael dies early in the books too, but that doesn't mean he won't be back later.
- No Fades was a disappointment, especially would have enjoyed seeing a Fade "obeying" Fain. Fain being let go by Perrin made sense to me, he was just negotiating to save the village, they were way outnumbered, and Fain has to be there later anyway so I understand why they didn't finish him there. Overall the battle wasn't as epic as something like Helm's Deep obviously but it's a TV show so it felt appropriately scaled at least.
Overall I thought the finale was pretty good honestly, after a mostly good season with one really good episode (Rhuidean). I liked seeing Lanfear using the True Power in the finale, and also enjoying the focus on Mohgedien whom I felt was underused in the books at some points. Also liked how the Black Ajah had trouble finding the a'dam because they were so sure it looked like that old painting they had, but in the end the real experience of a'dam by the good guys (or girls) means they know what to look for and know it's not a full collar, it turns into one after you put it on a channeler, that was pretty good. Also liked the mention by Elayne of Delving, and how they showed the beginning of it with her manipulating the balefire rod immediately in the correct way, because that's just her inate skill basically. Balefire I didn't imagine to be purple but the effect of destruction as well as the time-shenanigans it has due to the pattern-burn was cleverly done I thought.
Hope they get a season 4, it's not locked in yet.
