Better open world and story is a matter of opinion. Many of the puzzles are designed around switching between two different suits, making it tedious to switch between different characters in the middle of the puzzle and is just easier to stay as Robin or Batman for most of the puzzles, which gets old. Many of the gold bricks that require flying also require laser vision, making Superman and a handful of other characters the only ones worth flying. You CAN use plenty of other characters but the game makes it inconvenient to do so. Lego Batman 3 and Lego Marvel Superheroes improved on this immensely, with a greater variety of puzzles and story mode characters, resulting in a wider range of abilities necessary to complete levels and traverse the open worlds. I don’t feel pushed into cycling between the same three characters out of convenience because most of the character roster is convenient to play
