Just noticed....
In Batman Begins there was something majorly stupid. When Bruce goes to visit Carmone Falcone after his parents' killer got killed, Falcone proceeds to tell Bruce that Joe Chill told him his father begged like a dog for him not to kill him in which Bruce got mad. The problem is that Bruce was actually there so instead of getting mad he should've acknowledged & even brought up the fact that Falcone was lying.
Btw, I noticed it a long time ago but this is the only title I could think of for this thread. 😄
