"Long Time No See" is one of my favourite movies of all time (including non-asian ones).

Though the beginning of the felt a little rushed, I enjoyed this short series from beginning to end. It's a very interesting story that captures. The plot twist is no joke. There's no idolization of the underground which I find pretty important. The leads were well chosen, and I came to love Gitae's older sister. I totally forgot that she's such a good, accepting and supporting character. The chemistry between Gitae and Chisoo felt almost like you could touch it. Their complete incapability of taking their clothes cracked me up so much that I started sending lines of the dialogue to a friend.
The music mostly fits well. At times the combination of the visual imagery and the music almost sent me down from my chair because I laughed so much (at 4 am - everyone would have hated me for that). Honestly, I'm still laughing about that one bed scene.

Since I was re-watching this, I think I can answer this honestly. It's still great. I have watched "Long Time No See" two times about a year or two apart, and I remember having enjoyed watching back then just as much as now. I rarely skipped, which is a feat in itself, seeing as I start skipping a few seconds whenever I start feeling bored.
