Time to stir up some controversy! What fun!
Here goes:
I find the ACOMAF crew really forgettable
I'm sorry, but the characters just don't seem to have much complexity to them.
DON'T KILL ME. LET ME EXPLAIN.
I'm talking about ACOMAF. In ACOWAR, I did start to like Cassian, just because I ship him and Nesta SO FREAKING HARD. That's about it, and the only reason I remembered Cassian at the start of ACOWAR is because he wrecked one building. 
But I honestly can't really think of anything extraordinairy about the others in ACOMAF and even ACOWAR. Feyre was mostly occupied with Rhys, tbh. Actually Lucien had more to him than most of the Inner Circle.
SORRY, but I find them forgettable. Hope Sarah'll remedy that in the next series.
