What I like:
I personally enjoy the horror girl crush concept that Dreamcatcher is known for. Their type of concept is more similar to your everyday boy group concept and I like the uniqueness. I also like cyberpunk/80s concepts like what Everglow did for La Di Da and for a non kpop example, Blinding Lights by The Weeknd.
What I don't like:
I don't like overly cute concepts such as old Twice songs and stuff like that. I have to admit, I kinda cringe at concepts like that.
