My 2-year-old wasn't scared last summer, but my guess would be that if a child *were* scared, it would be more due to the overall atmosphere of the restaurant (it was quite dark -- hard to even see our food well) than the sci-fi clips specifically. My 7-year-old watched them and thought they were more funny than scary, though like your kids Scooby Doo is more her speed in general, but I don't think my 2-year-old paid any attention to them at all.
If you do eat there, I suggest bringing along a small flashlight to help check the table before you leave to make sure nothing is left behind -- because like I said, it's really hard to see, and with kids you never know what they might set down and forget about!
