1. The baby in the park, yes it can move in broad daylight with hundreds of people looking. Yeah, I wondered that, too.
2. Statue of Liberty, yep, the biggest statue in Manhattan wasn't even noticed and some how made it to Winter Quay and then completely stopped when Amy and Rory turned around away from it. Exactly. It was like that part from Ghostbusters 2.
3. The babies in the Cellar, oh lawd, the worst one that ruins the episode Blink. When the babies first stand up there is one that is looking at another from behind, its eyes are in clear view and it can still move. Kills Blink because then the Angels there would be able to move :/ Not until the lights go out. Then they can move and such, even when being looked at.
4. Graveyard #2 There is a point where (after Amy and Rory are from ages ago) the Doctor and River (Melody) are NOT facing the last Angel in Manhattan. Fail. That is all I have to say.
5. The locked up angel, the Angel should've been able to break the shackles, and was clearly not in anyone's sight yet did nothing. It was too weak to break them. Hence the fact that River was not sent back in time when it grabbed her.
This might be wrong, seeing as Angels often do look at each other,but there were a lot of errors :/
