The Gun on Ice Planet Zero (1) - S1-E8
Revealing mistake: When the 'snow ram' loses power and stops, the crew jumps out to see what has happened. The snow surface behind the ram is undisturbed and trackless, as if the ram has been stationary long enough for its tracks to be erased. This is because it is actually on a set and has not moved at all. (00:34:00)
The Gun on Ice Planet Zero (1) - S1-E8
Plot hole: The borrowed (oh, all right, ripped off) plot of "The Guns of Navarone" does not translate well here. The premise, that the rag-tag fleet must pass through the "narrow corridor" guarded by the pulsar gun, is ludicrous. We're in outer space here. Outer space is very, very big. We can fly around one lousy little planet, no matter how many Cylons are "herding us" toward it.
