Not really. I mean they all start edgy and negative, but I found that later on they mellow down depending on if you treat them nice or not. If you try to save Shadowheart for example she is much more civil, and I think Lae'Zel's writer also said in his stream that he will adjust Lae'Zel's reaction according to the time you've spent together on Nautiloid (since the tutorial was implemented later on before her dialogue was revised).
I do like that you're not expected to act as a doormat when they are being insulting, i.e. you can insult Lae'Zel back for her nose remark and she will not disapprove.
What part of Wyll or Gale are edgy or negative?
Even Shadowheart is positive unless you pester her too much with personal questions.
How trustful of people would you be if you just escaped a mind flayer ship with a tadpole in your brain? Its also true to the lore that Clerics of Shar are very secretive, she is perfectly in character and normally nice to everyone except Githyanki unless you try getting too personal with her.
