That is true; some differences are simply neutral, not better or worse. If someone likes the Land Before Time movies, that by itself does not signify anything about them one way or another. Also, keep in mind how popular and long-lasting a series this was. I don't think it is truly abnormal to have heard of it, at the very least. Now, are there some abnormal things associated with the series, such as being obsessed with a character? Maybe. Even so, I don't think that makes one better or worse, unless it becomes an unhealthy obsession. How one defines "unhealthy obsession" is very much open to debate; I don't have much to say about that.
Another cliche I don't like is how crashing cars ALWAYS seem to explode in movies. Having seen cars crash before, I can tell you that explosions are the exception and not the rule when a crash happens. And thank goodness.
