I feel your pain
Sitting through terribly done projects has to be one of the most terrible parts of school.
I have had to sit through many terribly done projects (not Tolkien related though), where words were butchered, and people acted like they knew the topic but they just did not.
Like for example I had to sit through this one project on Italy, and the person pronounced the name "Milan", "Mi-LAN". They made it sound like the city was in China instead of Italy!
I have had to deal with many people who acted like they knew Tolkien too but didn’t. I would tell them that they were wrong, correct them, and then feel so sorry for them.
