no it is not overrated .

It's the best batman game compared to a list of at least 25 games ranging from good to mediocre .

Even without considering the license , its history and its appeal , on its own , as a game , it was something the closest thing we had in years (till recently) to a great (traditional) metroid/castlevania kind of experience on home consoles .

The length of the game was just right , because of an impeccable sense of pacing and flow .

It's also the best use yet of unreal engine 3 on consoles . There are a few games that are prettier , like Mass effect 2 , or mostly released afterward , but almost all of them got technical issues ranging from minor to big , that didnt really affect Batman in comparison , even on ps3 .

The battle system is intuitive ,very easy to get into, but gotta be mastered . Something most recent beat them up cant even claim .

At last the voice acting is top notch .

I dont think the game is perfect , far from it , but it deserved its accolade .

It's the word "overrated" that seems quite overrated and abused around here .
Most people the game rallied arent even huge fan of Batman and had between none to very little experience with the comics , how would an overrated game do that ?

It is THE BEST super hero game made!
