It's not the greatest thing ever, but it definitely has had some quality moments and absolutely is a great companion to the game.
One thing, though, that has struck me about it, in conjunction with the game: An unhinged Superman can be really, really scary. I mean, absolutely creepy on any number of levels.
It's not that we haven't seen the archetype before -- there's been plenty of Ultramans and the like over the years.
But there's something really, really creepy about an actual Superman who is...basically...well...he's...crazy. It's...weird.
If you're playing the game, I do recommend reading the digital series -- again, it's not perfect, but it is a solid complement to the game.
