Naked teen scares two guys in stockings with his huge sausage.
Despite that, the deli-meat scene and others like it were still fun and choreographed well, so the potential for great action was always there, but juuust out of our reach. It doesn't ruin the movie, but it's a tight-rope walk between enjoyment and turning the movie off to replay Turtles In Time for the Super Nintendo again.
But then near the end, Shredder drinks a mutagenic plot device, transforming into a hulking monstrosity called the Super Shredder. His introduction is to badass-ly punch through the boardwalk the turtles are standing on, which is like opening your handshake with a clothesline. And in that instant, EVERYTHING starts to make sense: The action so far was a bit too PG because they were saving all the awesome stuff for THIS moment! THIS was the apology for the anticlimax of the first movie!
The turtles finally face their gratest enemy.
There was more to it, though. Early on, Master Splinter says to his kids: "You are ninja, you must always practice the art of invisibility," and, holy fuck, he was obviously talking about this fight. Clearly, the turtles couldn't take on Super Shredder head-on so they'd have to spread out and attack him from the shadows, slowly chipping away at him like a Dark Souls boss, presumably with non-meat nunchucks. Yup, this fight would finally bring the entire movie together.
