Bigger is not always better.
Dark Knight Rises is not a bad film. It just manages to fail in ways that the previous two movies had not. The list of flaws in this film goes on and on (The dumb Robin reveal, the absence of Batman, the way Catwoman's character doesn't match the atmosphere established in the trilogy. etc.) Characters don't feel flushed out and worst of all, the stakes don't feel all that high in Gotham/ No Man's Land. Batman and Co. seem virtually indestructible, each one of them making it through the crumbling city in a different, ridiculous way. Honestly there are a hundred articles online pointing out the glaring flaws in this film, so I won't try to replicate theirs. Instead, suffice it to say that the conclusion to the trilogy was both decent and disappointing.
