Continuity mistake: Near the start, Roark is down in the drain and part of his mask melts. When he is back at the surface the mask is in perfect condition. (00:15:00)
Suggested correction: It was not a mask but some equipment on his chest near the radio, which looks pretty burned, when he finally gets outside.
Character mistake: When they're literally watching lava creep down the street Roark says "whatever this stuff is" (something like that). 2 things: 1) how does he not realise it's lava, and 2) although it's weird to have lava in LA, Amy already told him that lava could push through from the tar pits, so he should have been able to figure it out.
Suggested correction: Even if he knows what it is, he is still in denial and just doesn't want to say the name of it, as it's uncomfortable to say.
