Pretty good movie but full of holes

1. When Kent tried to cut the suit off with a saw, he broke the blade, yet Peter Stormare had no problem at all chopping him in the shoulder with a meat cleaver. Why?

2. When the clown went to Chuck E. Cheese, they showed a yellow slide that ended with a "play pin" full of small plastic balls for the kids to play in. A kid was in the balls and got out saying "Somebody Peed" because his feet were wet, only when we saw his feet, that wetness was caused by BLOOD. If that's the case, why was BLOOD under those plastic balls, yet the slide and all the plastic balls were completely CLEAN????..Where did the blood come from?

3. When Kent was at the hotel and the saw blade went through that kid, his wife showed up at the Hotel (how she knew where he was, there is no explanation), walked up to the door to the room Kent was in (how did she know what room he was in?), and when she was about to open the door, we see that she had a HUGE RING FULL OF KEYS?...I don't get that....i would think Kent would have all the keys to the hotel rooms....we know that he had at least one, because he got into one of the Hotel rooms but why wouldn't he have all the rest of them?.....and it appeared that nobody was staying at the Hotel at the time at the time because it looked abandoned...i assumed the Hotel wasn't in business at the time and that Kent might have been "restoring" it, because there were no cars in the parking lot other than Kent's....yet that little kid showed up out of nowhere and went into Kent's room...also, when Kent was planning on falling into the saw blades to chop his own head off, WHY was the door to the room unlocked??...you'd think he would lock it, considering what he was doing...the kid just walked right into the room...

Inconsistencies like this is why i wouldn't give the movie a great review....If i can see the problems, why couldn't the people who made the movie see them?
