YMMV / Say Cheese and Die!

• Accidental Aesop: Don't take anything from a stranger's house. Even if that taken object can be harmful to others like a gun.
• Harsher in Hindsight: Spidey trying to kidnap Greg and Shari seems cruel reading the book for the first time, and then you move onto the sequel. Being more familiar with the cursed camera, Spidey probably knew Greg would pull stunts like that and was trying to prevent more misery. He failed.
• Jerkass Woobie: Spidey stole the cursed camera from his partner out of Greed to gain fame and money and attempted to prevent Greg and Shari from leaving, claiming they knew too much, but also the camera ruined his life, taking away his job and family.
