This episode is not about dinosaurs invading anything, really; it's about something completely different. Calling this serial Invasion of the Dinosaurs is like calling the movie Titanic something on the lines of Steamy Lovemaking in Cars. Sure, it's absolutely a small aspect of the movie, but it fails to capture the bigger picture.
