First of all, i want to clarify that i haven't watch the original movie. So maybe thats why i enjoyed this movie a lot more.

1. Okada Junichi and Ayano Go
The acting in "Hard Day" is amazing, especially Okada Junichi and Ayano Go. Junichi usually plays tough characters, but here he's a vulnerable officer, showing off his acting skills. Ayano Go plays the villain so well with twitchy eyes and subtle moves. You can feel his massive anger, especially after a run-in with his father-in-law.

2. Seeing Both Views
The movie cleverly shows the same events from two perspectives. The villain seems calm from the outside, but when you see things from their point of view, they're just like everyone else. It adds a cool twist to the story.

3. Ost
If you have watch the Movie "Sicario", you'd now that soundtrack in this movie has the same vibe to it, and that's how you now its a good soudntrack.

4. Unrealistic Moments
How, like how the heck did he surived the bomb with insanely minimum damage to his body. He should be burning to hell by now. But then he even got the strength to drive to the vault location? Hell nah.

Overall, even with some unreal moments, "Hard Day" is a simple and thrilling movie. I was hooked from the beginning to the end. The acting and the dual perspectives make it a ride worth taking.
