I don't understand all the Nick hate?

Are you all just going by what the other men have said? Because I certainly have not picked up on any smarmy vibes from him.
Nick has been my favorite from the beginning. He seems genuinely sweet. And what comes across to the other guys as cockiness to me just comes across as confidence.
So many bachelors/bachelorettes say the same thing as Nick "we have a connection that I don't think anyone else has..." and they don't get thrown under the bus for being cocky. He also has said he's not there to make friends. I agree 100% - you're there for Andi, not for any bromance.
I'd much prefer a fully confident guy than an insecure, whiney, needy one.
I haven't seen anything else that points to Nick being the bad guy, other than his confidence in his relationship with her and his being there for Andi, not the guys. I REALLY feel the producers are egging the guys on and creating drama in the house when they're really isn't ANY.
