I love TEIS, but the first three episodes were a bit of a mess. If you are really familiar with the source, then they make a lot more sense, but going in blind, it feels like three different shows (they did quite a major rearrangement of story to start the series). The point at which most people say TEIS gets into a groove is by episode 5. So, if you want to give it a fair shake, get through that point (which ends the first arc) and see if it is landing with you.
