I'm writing this after my rewatch of this. I 1st watched it 2 years ago and I really loved it but tbh I slightly couldn't remember why so I needed to rewatch it ;)

I'd say this was a perfect time loop story, it was only one and a half hours and so much happened! usually it takes movies one hour to get to the point and then they spend the rest of the time "wrapping things up".
but here as soon as Joon Yeong leaves the airport things start to move along. and what's more thrilling than a father repeating the death of his daughter every day while he can't change it? a more desperate guy shows up and claims to be stuck it the same time loop.

as a time loop enthusiast, I usually only see 1 character stuck in time so the story is only about them, but this really kept me on my toes with how the story progressed. and even though they were technically repeating the same hour every time, the scene development differently and well.
also, since it is a time loop I think it's the only acceptable time to be twisty without trying too hard just to be "unique".

since it is my 2nd watch I'd say it's worth a rewatch, it's actually more intriguing when you know what will happen. also the acting was amazing from everyone.
