3/4 translates to 75/100, while 3.5 is 88/100, I'd say that's a difference lol an entire grade, from C to B+. And the reason why I cited that is because that's how Bruce learned about Bane, from JGL's character telling him about him due to Gordan having learned his name, but he doesnt in context to the movie since as you said, the movie cut that scene. Also, the fact that Bruce got back to Gotham at the end with little to no explanation and his spine healing so quickly. And no one really connecting the fact that when Batman disappeared Bruce disappeared as well, and when Bruce reappeared Batman reppeared as well.
Hey, if trying to make the grade sound better helps you out, then by all means, think what you want
I would do the same if I was in your position.
And it doesn't matter what Blake tells Bruce. The audience is already aware of the name of Bane and if the CIA also knows a thing about him, then you could even suggest surely Gordon would even if we don't see any mercenary mention his name. Plus, Gordon brings up an underground army as well but the way Gordon looks around, he only sees a few people. Go ahead, complain about that too, lol.
And why bring up other nitpicks?
We don't need to see how Bruce arrives at Gotham because it was special that Bruce first shows up talking to Selina. But look at how Bruce is a trained ninja and even the Special Forces members got in Gotham pretty easy. Using your own imagination won't hurt you, just like what you want to believe on what Blake does at the end of the film.
His spine healing from a protruding vertebrae is a bit out there since it heals in months while he's hanging on a rope, I'll even agree to that, but I'm totally fine with that idea. We got the idea of the whole Knightfall arc where Bane breaks the Bat and Bruce heals. I like to view that the Pit does hold some fantastical ideas in it though as Bruce heals, his knee seems to have gotten better, he had a vision of Ra's al Ghul.
It only takes a chance for someone to talk to Lucius Fox who could say when he last saw Bruce, which was the day before Batman "died". And that's when Bruce could have died, the day before.
Also, I'm fairly certain a lot of the critical reception was slightly heightened due to the hype created by TDK, which even critics fall under, proven further when it comes to critics who even said TASM was a decent-good movie, but rated it lower due to it being a reboot. Critics can be just as biased as the common folk.
Very weird way of thinking it besides the notion that critics loved it as a finale and all, but okay.
