Of course the first ending lost in paradise slaps on all levels. The up beat catchy tone combined with the low detail and absolutely charming animations of the characters as they rotate onto the screen is a blast.
Ending 2's song isnt as catchy but when paired with the visuals it instantly comes together to create this somber nostalgic short animation. The transitions from cell phone screen to actual events make it feel like someone reliving an old memory of days gone by. The scene then transitions through these haunting luminal spaces until it cuts to the camera again and one of the friends beckons the camera man to join them and be in the moment. There's a look on his face where he's almost in awe almost self aware that time with his friends in precious and fleeting. Then the luminal spaces fill up with people using them and transition from haunting backgrounds into warm memories and spaces.
The ending gives off an air of bitter sweet nostalgia. Theres something so haunting and sad about it while also being so uplifting and sweet. Seeing people hanging out, being in the moment, and enjoying relatively mundane but enjoyable time together doing chores or hanging out doing nothing.
It's celebratory of life almost in the way a funeral is with the remembering of good times past.
