O.K. so I got to watching this series simply because it has Spider-man on it, but from the very beginning it felt more like a Buffy the Vampire Slayer spin off or something(without demons of course). Now, don't get me wrong, Buffy was a good show that I enjoyed but Spider-man should be Spider-man. not a Buffy wannabe.
Most of the important Spider-man characters are there, but they all have the look and personality of Buffy characters... So this series completely Feels inadequate for the long-time Spider-man fans.
But if you're new to the Spider-man anything... you should check this out, it has some really cool fights and you get the gist of why Spider-man is such a cool character.
As for the graphics.. eh, sometimes they look incredibly cool(areas with extreme shadows and lighting A.K.A. Night), and then again other times they look extremely ugly(Pretty much whenever it's not night). So you're getting a little bit of both quality extremes. ^^
