Unpopular opinion: KissXSis is the most overrated film of the decade
Rewatched KissXSis last night and noticed even more plot holes than the first time. The motivations don't track at all once you stop and think about act two.

[Spoilers] Can we discuss that absolutely baffling ending in KissXSis?
Director clearly thought KissXSis was deeper than it is. There's a difference between ambiguous and unfinished, and this leans hard into the second.

The cinematography in KissXSis is doing all the heavy lifting and it shows
Honestly, KissXSis would be a tight 95-minute movie. Instead we got a bloated runtime padded with B-roll and lingering shots that add nothing.
