If you watched QH for certain actor and can't see beyond the actor then you should give it a skip. However, if you were attracted to QH due to combination of factors such as story, acting etc then may be QH is worth your time. It is prudent for you to check few episodes and make your own decision as not everyone like the same color to the same degree.
I am still watching QH, few episodes impress me and few disappoint me but that's how QH was always been, pre or post KSG. While KSG was phenomenal as Asad, RV is not bad either. RV brought a softer touch to Asad. There are for sure some changes to Asad's character, he learnt to smile and got bolder romantically and in my POV changes looked as a natural extension and are driven by the phase of Asad in his life at this point. Asad is no more lonely angry young man, finding true love and getting married to Zoya must have mellowed his feelings of abandonment due to abbu's betrayal that made him a bitter angry young man. He is now enjoying his newly wed status and happy in life, therefore, the anger and ruggedness of the character took a back seat and RV is doing his best as Asad who is now evolved as a caring and loving husband.
