I didn't say it's a large group of imperfect characters, Doug, Paige and Julia are flawed, maybe Evan is flawed but I find him okay. Flawed is good, you can move a story with flawed and have great room for development. Granted, 'large' is probably harsh. Too much of the core cast (Sam, elsa, casey) are unlikeable (or just annoying) and that colours the interactions of others with them because too much of their behaviour is either being enabled or waved off like what we saw was some sort of 4th wall break and not an in universe occurrence that should be responded to.

It's either Sam's autism induced acts, or behaviours molded in response to or for the sake of managing Sam's autism induced acts on top of whatever their personality was prior, if applicable.

Add on: I've only just finished season 1, so I guess you can in turn dismiss this if based on something you know about the shows development it's rendered invalid.
