Definitely. I heard some people complaining, but I've watched and rewatched the DVDs many times, and I think it's a really good show. Hopefully it will continue.
SMU? No, that was canned because Fox wanted every Pokemon ripoff to be aired three times a day. So there was no room in the schedule to accomodate that and SMU.
I think I heard that they did get some episodes of season 2 completed, which I hope they could release with season one on DVD, so I can find out how that series ended.
Spider-Man Unlimited was horrible. I hated the machine suit he used and it was so dumb that he was on another planet.
I was just watching Spider-Man Vs Doc Ock DVD. The animation bothered me for a bit because I remembered it looking better, but the stories were still good. I wish they would release a box set of this show like Batman:The Animated Series Volume 1.
