Yeah, the take on Bane in B+R was totally insane. I mean, as bad as the movie was, and for as little good as it did, the depictions of Freeze and Ivy were pretty faithful. Whereas Bane, who iirc at the time was still in the running as Batman's greatest enemy, was turned into a ridiculous, poorly-SFXed henchman.
On the plus side, this means that Bane could be more readily utilized in a future film without the taint of B+R, unlike Ivy or Freeze. (Not that I think Nolan, at least, would deign to use Ivy or Freeze anyway, for reasons given above.)
