At the time this episode came out, without knowing what we now know, it probably would've been a solid 8/10 for me. Lays some ground work, introduces characters that will become more important later on and shows us Eren's determination. The highlight of the episode upon revisiting would definitely have to be the conversations between Eren, Reiner and Bertholdt, as they contain a lot of foreshadowing and become quite sad knowing what is to come. And despite Episode 2 having a higher rating, I actually think this is better. Of course it doesn't beat the explosive series opened though.
