Better than most of SYFY channel made movies. The acting is actually good. Maybe I missed it but what is up with the little (?) brother. He seems kind of needy and not all there. The special effects are okay. I don't understand why the rocks blow up but hey I didn't write the script. You can see certain occurrences coming before they happen though. Like the lighthouse keeper getting killed by his own lighthouse when it is hit by, gee, a stonado and collapses on him. Then there is the rebellious teenage daughter, you can tell she is going to do something to upset pop. Told to stay home with baby brudder she takes him and they go to a football game. So of course the stonados hit the stadium. Now after the day before when the harbor and such were destroyed, who in their right mind would still hold an outdoor event? Well the NFL after JFK, but who else? A decent enough movie for rainy day.
