Season 4 had good bits, but it wasn't the best.

I did like Elsa's connection to Emma and how she helped her control her magic.

That was one of the things I liked too I also really loved the Rumple/Belle/Will stuff in 4x19, "Lily" (Rumple was awesome in that episode!). Rumples scenes with the QoD (especially Maleficent) were great as well. Episodes 1, 6 and 11 had some nice scenes too.

And that's pretty much all I remember about S4.

Yeah, I feel like you could skip most of S4 and not miss anything too important. I don't think the Frozen characters or the Queens of Darkness (except Cruella) were even mentioned again after S4. I think episodes 11, 17 and the finale are the only ones you need to watch because they explain Rumple's dying heart (which led to the events of S5) and the return of Zelena. Also 12 and 18 for Cruella (as we met her again in S5 and S7). Everything else in S4 is just nice extra. But then, I may be biased.

I really liked the QoD scenes with Rumple as well, some of them were . about the scenes in 'Lily' Seamstress

and about S4 as a whole..
