That was a very good premiere. Felt like it handled most things really well.
Still not sure I fully buy into the conflict with Dylan and Norma at the end of last season. I think it was that Norma had grown to care about Dylan and wanted him to stay to help look after Norman, but she kept letting Norman.... get away with murder. *rimshot* I mean, I guess I get where he was coming from, but the end result of completely abandoning them, even to move with Emma, seems rather extreme despite being the implication from last season's last episode(s). I'm also a little surprised Emma didn't seem aware of how the previous season ended, either. Unless they were covering it up to Caleb, but that seems unlikely.
Caleb is another piece I sort of struggle to pin down. I fluctuate on how I feel about his relationship with Dylan.
Oddly, don't feel like there's too much to say about Norman. It's basically what I expected, but done a lot better (overall) than my cautiously high expectations.
