Continuity mistake: When Luke grabs a beer from the mini bar in the hotel, there's a lot of beer foam in the top of the bottle. In the next shot, when Luke's sitting on the bed, the foam is gone without taking a first sip.
Other mistake: After the daughter visited with her mother for the first time, she is reviewing the footage with the priests. No such camera angles were taken for what they reviewed, only an overhead room camera would have been available.
