Revealing mistake: When Aaron is pinned down by the sewer zombie, the zombie actor's neck can be seen below his head mask.
Suggested correction: I went back and watched this scene several times, and I think the OP is mistaking Aaron's hand on the Walker's neck as the gap in the mask.
Revealing mistake: When Morgan stabs the walker which is hanging from The Tower, the blade enters its lower head, but the blood can be seen coming from above the hairline. (00:25:30)
Suggested correction: I can see where the confusion is. If you watch it normal time, it looks like he stabs him in the cheekbone. But in slow motion, you can see the blade go into the top of the skull.
Revealing mistake: One of the saviours goes to shoot Carol but Morgan shoots him first, about 4-5 times. The man goes through the motions of being shot and we get a good view of his body/chest area and head, but there are no bullet holes.
