I disagree with others. The vine animation is a random mess. The 'all the vines growing in a single day' is unrealistic. If you were going for the symbolism of day and night, it's poorly executed. The instant transition from the old time period to a sidewalk in the post-apocalypse time period is too random. It would have been better, for example, if you slowly zoomed out from the old scenery to the TV to the building and then to the sidewalk, if you catch my drift. Overall, this random mess with incoherent transitions makes for a weak narrative.
