I'ts like watching a Kim Possible movie. =)
Edit: Which I actually recommend. The whole series is great.
It is. Superbly fun little show. If you like it, make sure to see Gravity Falls. Best animated show since Kim, and it has a somewhat similar humor and adventure style.
No offense and I have not seen the show but I am litirally judging by the cover.
The show just looks....average and predictable.
From the look of the art style and the mere premise and the certain characters I have seen.
I feel I have already watched the show just by imagining it.
Now that is out of the way:
If you like Kim Possible then you will enjoy Danny Phantom.
