I'm still waiting for someone to say a blockbuster that was better than DK this decade and no I don't think CR was as good as DK.
Depends on how you define blockbuster really, does $120million domestic count as a blockbuster anymore? That's how much Inglourious Basterds made and I would very much argue that was better than The Dark Knight, not just something I prefer but better. If we were to define a blockbuster as upwards of $100million domestic, I imagine there would be people out there (though not I) who would make a case for the Lord of the Rings series, the Bourne films, Road to Perdition, Walk the Line, Benjamin Button, Star Trek, District 9, Watchmen and so forth.
If you were to term IB as a blockbuster than yes I would say it was considerably better than DK but I'm talking your Star Trek's or LOTR, I enjoy the Potter franchise but I don't fool myself that they hugely quality films, I just think DK did something that very rarely blockbusters do, it's not perfect but it leaves most tent pole films looking pale in comparison.
Bourne you could argue but it seems like they stuck to a format for all 3 films with the first in my view being the strongest of the pack. Ultimatum was no better than the previous one yet for some reason it got touted as one of the best of the decade, DK had far more going on in it. If you thought Burton's films were good and try to defend Batman & Robin then I guess DK will confound you in comparison to those absurd pantomimes.
