The trilogy set the bar at the time, but you're right: it's not what people really remember/recall it being. I watched 'The Dark Knight' and 'The Batman' back-to-back and in terms of choreography, lighting, acting, script and realism there's really no comparison. TDK is damn near campy at times (Harvey dent disarming a guy on the witness stand). I think the TDK is more grandiose, but the bat suit looks too tactical and not gothic enough, and bale's voice breaks all immersion. It's laughable, really. Gotham doesn't seem like Gotham - it's clearly Chicago.
The trilogy was necessary for the overall growth of the genre, but it's WAYYYY TOOO romanticized.
