Troll 2: They're Eating Me ALIVE! (A Theory)

Okay, so I just re-watched Troll 2. And, I know, I know, it's "so bad it's good," but hear me out. I think maybe... maybe... there's a deeper, slightly more intentional thing going on than just complete ineptitude. Like, think about it. The goblins are vegetarians who turn people into plants to eat them. That's... weirdly specific? Is it a metaphor for the way consumerism 'vegetizes' us, man? I'm not saying it's good commentary, but is it there? And then there's Grandpa Seth. He's clearly a figment of Joshua's imagination, right? But he's also the only one, besides maybe the townspeople (who are obviously in on it), who understands the rules. He's like a DM in a really, really poorly written D&D campaign. He knows the only way Joshua can win is through... sandwiches? The power of love? I'm not entirely sure what the hell that scene was supposed to be, but it kind of works. He knows the rules, and Joshua knows the rules through him. Now, here's where my theory gets shaky. What if Nilbog isn't a town at all, but a state of mind? Joshua is having a mental breakdown. The goblins are representations of his fears and anxieties about growing up and leaving his childhood behind. The green goo is just, you know... goblin goo. But the idea of the goo, the way it turns you into something else... It's a loss identity! I think the director's name is Claudio Fragasso, but he wanted to remain anonymous. What was he trying to say? Look, I’m probably reaching. It’s probably just REALLY bad directing and a horrible script. But the line, "You can't piss on hospitality!" just keeps rolling around in my head. Could this movie actually be a secret masterpiece? I doubt it. But, “They’re eating me alive!” I'm just throwing it out there. Let me know what you guys think.
