Some thoughts:

They blew all their budget on the Titan assault on the inner door. Cool sequence, and much better than the similar sequence in the manga that was so short people routinely missed that it actually happened and were confused by the fact that Wall Maria had fallen.

Eren's Titan hatred has sure consumed his life. It looks like all three of the kids are PTSD'd out the ass, in various ways: Eren is a lunatic, Mikasa shut down, and Armin is a whimpering pisspile. You'd figure crazy Titan bloodlust wouldn't be that uncommon among the people after such an attack though. Also as various commenters on other sites pointed out, yes, the trio are very archetypal at this point. Give their characters some room to breathe though, and don't judge them too harshly off just these two episodes.

As others have said I love how the Titans look, move and sound in the series. Their weird sexless and ageless appearance, the shiteating grins on the faces of some of them, etc contribute to a very grotesque feel to what otherwise could just be Big Cannibal People.
