Game deserves far more credit than it got when it came out. It's a decent, old school beat-em-up, nothing fantastic, doesn't reach the same level as say, God Of War and yet it's charming and hides some depth in it's rewarding gameplay.
It's not a long game, but that's a plus for many of us lately. Production values are above what can be expected from a game adaptation: yes, they could have used a little more variety in the environments, but everything else is fine. The models are good, animations are as well, enemies are repetitive but not to the point of getting boring... the cut scenes are awesome and won't make you rip your eyes off like with those super hero adaptations from Sega (Thor and Iron Man).
From the scarce reviews one can find on the Internet and even from this one, it might seem like it's a bad game, only not as bad as all other movie adaptations. WRONG! It's a good game in the same sense old school beat 'em ups were in the 90's. You turn this game on, kick some ass (gameplay is fun, I swear), don't get bored by 10 minutes long cut scenes and beat your game in 6-8 hours with a smile on your face. A must if your a Green Lantern fan or a beat-em-up fan.
