Any true fan of Marvel Comics would like this cartoon, despite the changes to the original concepts because it may have been too much for the kids (like Thanos, who is a nihilist in love with the embodiment of Death). These characters are the heavy hitters in the Marvel Universe, the ones that their mere mention would make the Avengers, the Fantastic Four, and the X-Men collectively tremble.
Considering the content, the grandiose characters, and the universal playing field, this cartoon had so much potential and could have been fascinating if it had been allowed to continue into the next season. This was very different from others of its kind, and it is sad to see it go so quickly, much like the Silver Surfer comic, which has always met with limited success. Even though Wizard Magazine listed the Silver Surfer the most powerful superhero ever created (two notches above Superman according to them), the character has just not had a lot of popular appeal...shame about that.
