I actually really like this one! I know it's not what a lot of people imagined it would be, but personally I found it highly enjoyable nonetheless.
It gives the audience more Bad Buddy (my deeply, deeply beloved), perfectly recapturing the magic of Pat-Pran dynamic while incorporating it pretty seamlessly into the ATOTS universe, which is no mean feat considering how tonally and thematically different the two shows are.
It also helped soothe my anger over the last three ATOTS episodes a little by focusing once again on what made that show great to begin with: Tian, Phu, and their complicated relationships.

It's not perfect by a long shot, some of the plot points are fairly ridiculous and, much like in the original show, the ATOTS half of the special introduces an interesting theme (how small annoyances and miscommunications can put a heavy strain on a relationship, as well as Phu's self-worth issues concerning the relationship) which it then fails to follow through on.

All in all though I think these episodes work a lot better than I expected them to and they are definitely worth watching at least once.
The ending is also pretty damn delightful, if that helps sway you.
