How this films has 8+ rating on IMDb is a mystery

Rating: 1/10 (10 January 2013)

I'll never understand how this film has a 8+ rating on IMDb. The first two weren't bad, particularly the 2008 one, but this finale really blows. The plot is poorly constructed and edited, at times making it impossible to follow, actors lazily played their parts, eagerly awaiting to say the line, get the check and get out. E.g. the scene where the main villain character dies after spinning her head in a jerky motion and shutting the eyes. You can literally feel the disgust on Gary Oldman's face as he watches this "acting".
Plot-holes are so ridiculous, I don't even know where to start: how does a nuclear bomb explode in a visible distance from a city and nobody gets hurt with a heatwave or radiation? How does a 12 million city has a single bridge of entrance? How does a handful of thugs run a megalopolis for months? Why does the main villain put the Batman, the prime target of her revenge, in a pit instead shooting him in the head? Where is that pit? How does a famished man with no money or other resources manage to magically appear from the said pit in a city surrounded by the the military on the other side of the globe? How... does the Nolan character get to make these "Epics"? I mean, no offense, man, but why don't you go making films like "Memento"?
