Not really. Sure a few of them are like that but that's once again an argument that seems to be used against every webcomic out there at some point (shortpacked much?). A few panels of him expressing his opinion doesn't make Lil'formers narrow-minded. For the record, I disagree with him on his views of Animated and the movie-verse, and I do find his strips stating those views to be rather poorly written, but they're hardly the bulk of his work.
Lil'formers isn't written to be a laugh out loud oh-my-god-that-punchline-was-hilarious type of comic though. It's just one panel, he draws something adorable and humorous in it every week. That's the draw. You don't have to like it, of course.
