Watch Gaki No Kisetsu (1997) Official Trailer

Don't think adults are always adults.

The camera sometimes runs with him, sometimes captures him from a bird's eye view, sometimes stirs him up, and sometimes gives him a live feel that is as intense as the protagonist's tension. The high degree of freedom of the camera eloquently captures the protagonist's inability, to be honest. The use of a hand-held camera to capture the scene of the mountain disaster is also effective and memorable.
