It's not like I said the silly and ridiculous bits were "smart" "creative" or "moving" I know they're bad. I acknowledge that. But it adds a sense of fun to the movie and keeps itself from getting too melodramatic. I hated most of those scenes on the first viewing, but grew to accept them on repeat viewings and get amused by them.
Look, I like Batman. As you see in my sig, I LOVED the first two Batman movies from Nolan. I had high expectations for TDKR, but it just didn't deliver to me. I was immensely bored by the characters of Dagett and Officer Foley. I don't want to watch Bruce mope around Wayne Manor for an hour. I don't want to see him sitting in a hole. I don't want the focus of a Batman movie to shift to Blake (With a completely flat performance by JGL) for an extended period of time. How did Nolan think those ideas would translate into entertaining or compelling entertainment? Why would he think people would like a Batman movie with almost no Batman in it?
Then there's the boardroom talk Bruce has with Lucius and Miranda. Nolan managed to make those scenes watchable in BB and TDK, but in TDKR, they just bored me to sleep.
TDK was serious, dramatic, depressing, tragic, exciting and terrifying, but admist all of that, still managed to keep a sense of fun about itself, from Batman's new gadgets like the sticky bomb gun, sonar vision and the Bat-Pod, the little bit with the kids seeing Batman fly by in the Bat-Pod, to funny quips not just from The Joker, but Bruce, Alfred, Lucius and even Coleman Reese. To top it all off, the movie had The Joker dressed up as a Nurse, even going so far as to wash his hands after talking to Harvey, then fiddling with a broken detonator.
The movie didn't become all gloomy until after Rachel's death.
But TDKR.. Just so darn melancholy. I felt like everyone was just whining in the movie. Bruce moping around Wayne Manor, grieving Rachel, Bruce being heartbroken that Rachel wanted Harvey, Blake telling a sob story of his dead parents, learning that [BLACKOUT]Gordon's family left him, [/BLACKOUT]Gordon in the hospital, Alfred getting teary eyed remembering Bruce's infancy, Bane talking about the despair of being in the darkness all his life, Talia angry over her father's death, Pavel dying, Foley dying, [BLACKOUT]Bane dying, Talia dying, Bruce dying.[/BLACKOUT] ALRIGHT NOLAN, WE GET IT ALREADY. IT'S A
DRAAAAAAAAMA! 
Spider-Man 3, for all its flaws, didn't try to beat the audience over the head "DRAMA DRAMA DRAMA" it kept a sense of fun amidst stuff like Harry mourning his father and wanting revenge, Harry getting a grenade to the face, Peter and Harry's friendship being broken, the inner turmoil Peter feels, from the guilt of Ben's death, the drive for revenge against Flint and his jealously/heartbreak over Harry getting together with MJ.
Eddie Brock's story had him pining for Gwen, wanting to be with her just as much as Peter wanted to be with MJ in Spider-Man 1, (One scene blatantly shows the mirror of Peter and Eddie..)
Peter: *snaps a picture of MJ* Hey beautiful!
-cut to Eddie Brock-
Eddie: *snaps a picture of Gwen* Hey beautiful!
A little on the nose, but you get the idea. Peter and Eddie are mirrors of each other, but while Peter's story ends happily, Eddie's ends in tragedy. Peter humiliates Eddie, costing him his job, takes Gwen away from him, and leaves Eddie with nothing but the desire for revenge. Unlike Peter, who learned to forgive, Eddie lets that desire ultimately destroy him.
For all its silliness, Spider-Man 3 still has seriousness and drama, with themes of redemption & self-sacrifice, and a moving final narration from Peter.
But yes, Spider-Man 3 is flawed and a bit cheesy. Not as ridiculous and flawed like Batman & Robin, but still flawed and cheesy.
Spider-Man 3, for all its flaws, I can still watch multiple times.
TDKR I can not. I don't even want to buy the DVD. Maybe I'll catch it on cable a couple years from now, but that's about it. I have no desire to watch it again.
