If going on a mad collecting splurge in Lego Harry Potter Years 5-7 was too much of a guilty pleasure to indulge in, you might be more comfortable with Lego Batman 2: DC Super Heroes. Even in Lego form, comic/movie icons don’t come much cooler than the Dark Knight. Even if he is stubby and spends most of the time sulking.
As long as you’re not expecting any dark plot elements like Nolan’s films, the 90s animated series or Rocksteady’s recent games, you’ll be fine. This is for fans who don’t mind a bit of fun poked at Batman. If the Joker was going to make a Batman game it might be like this. Everyone is so happy and cheerful, except for Batman of course.
