My Review of Sand Serpents
On the plus side, the CGI effects are fairly good for this kind of thing and the design of the worms is interesting to look at.
On the minus side, the worms are just too big. There should be giant holes all over the place from where they've surfaced. The ground should be collapsing in areas where they dug tunnels. And I really don't see how they would be able to reach up as high in the air as they do. It's like the snakes in Anaconda, but 10x worse cause of the increased size. I kept wondering after their first attack, how they could have wiped out the group of Taliban so near the building, yet left so little evidence behind.
The script and acting was about average for a SciFi movie (I agree that SyFy looks silly.) The monsters were really the only thing of interest.
