Yes, very

One can assume you know that because you read/watched/listened to the whole thing. I mean, if you hadn't, you wouldn't be entitled to call the whole thing boring, because you wouldn't actually know what you're talking about. You wouldn't want to make yourself look stupid, of course, so you obviously stuck around and wasted the 20 minutes necessary to decide it was boring. From where I'm sitting, it kinda looks like either it wasn't all that boring, or you are that desperate for something to do. Which kind of implies you don't have hobbies or friends to hang out with, further implying you yourself are boring. What an interesting train of thought. Also, leaving a comment helps the channel in the algorithm. If you think it's that boring, stay quiet and don't help them. That way, you won't be giving anyone reason to dislike you for posting unnecessary and hateful comments. Being liked and having friends is actually quite nice, you really should try it sometime. I know, the unknown is scary, but even the scary things get easier with practice, I promise.
