If you're not relatively knowledgable of and interested in Batman the game has alot less to offer.
Take away all the batman-ee-ness and its really just a competent stealth action game with a decent brawling mechanic so I'd say its integral to your degree of interest and enjoyment with the title. I was never a big comic reader but I was a huge fan of the 90s batman animated cartoon of which alot of the games characters and voice actors are taken from. The cartoon itself is highly beloved by anyone who was growing up in the 90s since it was one of the few cartoons back then that was dark, mature, well written and still stands up well today.
Its basically the first comic based game to be as good as it was too so that in of itself gave reviewers and gamers opinions of it a giant boost.
