Personally I am loving the Ankita-Naren track. Both of them are acting very well and their scenes are very out of the box and fresh, not contrived. There is an element of light comedy to all the scenes, so it doesn't really come across as tragedy, though it is one. I am eager to see how this story builds up- so far the writers have built it up quite nicely.
At the end of the day, all of us have our preferences and watch the serial for different tracks/actors/reasons. Just like you don't like Ankita-Naren track, I don't like the Purvi-Arjun-Ovi track cos it is one convoluted mess getting stretched for no reason, and most importantly bcos the writers are not handling it well.
