I didn't find it much exciting. I feel that this season and the previous season are has a bit of similar track. In the previous season too the girl gets married to a boy who use to live with her family and had a sister-brother kind of relation. This was the first turn off for me. And secondly in Reply 1994 I really wanted the Chilbong to the future husband but at last she end up being 'happily' married to that Trash aka Kim Jun Jae. I really enjoyed watching her chemistry with Chilbong. But one specific thing I liked the most about 1994 was the boarding house setting and the other several characters. The love and affection they showed and considered each other as their own family was the best of the drama for me.
Overall to say, I enjoyed Reply 1997 much more than this. It might be because I had my hopes held up too high for the next season to be even better but it turned out a bit boring for me.
But I am damn sure that Reply 1988 is best among all three though I still have to start it.
