Revealing mistake: After Casi runs the guy through the chest with the samurai sword, one can see that the two ends of the prop are not aligned, appearing bent.

1 revealing mistake - chronological order
Continuity mistake: The garage door was raised about a foot, but views of Craig sitting on the floor after he hit Lea show the door up about three times as high (to his nose), letting in more light. (01:17:52)
Trivia: "Singularities" are infinitely dense points. When something is compressed to the point of having a volume of ZERO, its density is thought of as being infinite - in other words, a "singularity." A typical example is the inside (center) of a black hole. A huge star - that once had a large mass - was reduced to nothing, but that "nothing" has a density that is infinite. It is at a point of "no return" (an event horizon), so is not visible. BUT "naked singularities" could exist - and be visible.
