I'm now 18 years old, and I still love to tune into Jetix and watch Totally Spies, especially now that the new series is being aired.
A good show for me has good characters, and Alex is my favourite of the girls, always has been, always will be. Now that they are all at university, I think it just adds to their personalities and adventures.
The storylines are always good, with great action scenes, and this is a reason to watch.
One thing I don't particularly like is the fact that Sam, Alex and Clover are the stereotypical image of American girls, but then again, you can't imagine them all being obese tomboys etc etc.
Overall, I've been a fan of this show for around 4 years, and I still love it :D
