And can't consider the episodes of Gadget and the Gadgetinis best, since the series had a little of disrespect with the original one. Still, there are episodes that I really like
Don't Call Me Gadget - The first episode that gave me a lot of questions, like where were Brain and Chief Quimby, why was Gadget working with some new "jerk" guy and who were those two robots. However, because I haven't watched the original series for long on the time this new serie came to my country, I was really happy to see Gadget again, even out of character. Not to mention, badass Gadget is awesome in this episode.
Looming Las Vegas - Don't know what to say about this one. Somehow I liked it.
Nice Guys Are Finished - Remember when I said Gadget was out of character compared with the original one. Well, this episode prove me wrong, but only this episode. Although Gadget is still stupid, he at least shows better at the end of this episode.
One Too Many Gadgets - Clone Gadget is AWESOME
The Wuzzley Affair - I don't know... just found it cute
No Such Things as Ghosts - Ok, I lied by saying Gadget was a little better on episode "No Guys are Finished". In this one he's also a little better.
Nozzaire's Day Off - Found it cute too
The General's Daughter - I think this one is one of the best episode this serie has by many, including me.
Help Wanted - Reminds me of the episode "Gadget's Replacement", but least sadder.
The Ultimate Weapon - Finally we see Gadget crying!
Reality Bites - Found it cute as well, not to mention the photos on Gadget's room (original series spoiler alert)
Prison Cruise - Cute too
No Brainer - A very very painful episode, and I don't need to tell why
But still it was good to see Brain again
Super Boss Gadget - Gadget as a boss? Sweet...
Not to mention we see Quimby, the only character that is not out of character.
Erasing Gadget - We didn't got the past we wanted, like if Penny was adopted or if she had real parents, but it was nice meeting Gadget's parents.
Claw's Nephew - Another episode considered to be the best by many, including me.
The Comet, the Unicorn and the Bad Gadgetinis - Just love Fidgit and Digit being bad.
