This is probably the most famous “bronze-age” comic (together with ASM #121) as it features the first death of an important Marvel character, Peter Parker’s girlfriend, Gwen Stacy. But I did NOT like this issue as a kid. Not only was Gwen’s death disturbing (that “snap”), Spider-Man loses control and nearly beats the Green Goblin to death. Spidey stops himself, but the Goblin still dies when his sneak attack backfires graphically. This kind of storyline became common in the late 80’s and early 90’s, but for an 8-year-old boy in 1973, this was way too dark for my tastes. I ended up trading this issue for another comic.
