I seriously doubt the Asylum cares considering they also created masterpieces such as Snakes on a Train, The Day The Earth Stopped, and Transmorphers. Also there are many movies about giant asteroids (Armageddon, Deep Impact, Etc.), it's not just about the idea it's about the execution.
That said, yea you can skip this one just because it's so bad it's laughable. Though since it's so bad it's laughable you might not want to.
