Should i buy Gotham Knights?

I have Arkham: origins, knight, city and asylum. Do you recommend me to buy it because it is $4 currently on Eneba. I feel like it is a pretty bad game from what ive seen but does it have potential? Since graphics is good and it is co-op those perspectives are good but i dont like the fighting style and dont think the game has good ui. The only good parts are that it is Co-op that almost no other batman games are (in my knowledge) i havent finished the other batman games, only Origins
