When a show starts people don't know what to expect from it. The show is fresh and new. However, as a show develops everyone has different expectations from the show. Some might find it slow (like myself), others might want the orginam story to continue, some might want a love track to build up etc. This doesn't mean a show should end. It just means the show needs to work on the viewer's expectations.
I personally want Shali relationship to develop more quickly, two have Nanku and Majri return in some shape or form and three Zee to promote Agle Janam more instead using Laali to promote other shows.
