Just another "genious kid" cartoon, that doesn't add anything for the formula and actually has only two good things that makes this worth to watch:
FEW of the songs. The key word is few
And everything related to Perry and Dr. Doofenshmirtz. The substories related to these two are some of the most hillareous material you will find in the history of Disney cartoons, that makes you wish that this show was about them, but no, they are overshadowed by the boring 70% of a normal episodes, and sometimes they are not even on screen. The show doesn't really holds up, i can't recommend it, even if it is for these two.
