Lots of invalid points... You can take a quick look at the current top comments, or I'll just copy them.
"While this is pretty funny several of these are not mistakes, they are just you not understanding someone. Like Talia "helping" them find the bomb. Did you forget that they found that truck empty? Oh yeah! Because Talia tagged the wrong one. Also, Blake knows where to find Gordon because he puts the dots together when he found the body of a boy earlier at the sewage ducts. Gordon was in the same place. Called good logic not flaw. Also, they didn't blow up the bridge for food and supplies."
I will agree that some are just plain stupid, like him finding out about Ra's Ghul in his own hallucination.
