Lakorns back then had a larger limitation to their lakorn episode so they did have to drag until episode 20-25 etc. Now it's tone down to at least 13-16 episode per lakorn. So I don't think it would drag as much even though at 13-16 episode some lakorns do tend to drag also.
The old version the costume was very nice. I haven't seen the whole wardrobe for Princess Saengfarng in this version. I hope the clothing are more traditional, seem like now adays traditional clothing, the top cloth they like to make it shorter so it reveals the belly, I prefer it cover, it looks better that way.
