They put instakill platforming sections in a beat 'em up.
You can tell Konami tried to be creative with some of the bosses & levels. There's even a batmobile stage. However, it's generally a mundane affair due to the limited pool of enemies and Batman's moveset. It's just not particularly exhilarating, exhausting itself before the end of each playthrough. Maybe if Konami had taken more liberties from the movie it would've been more interesting. Not offensively terrible, just boring.
