I could say this show is a disgrace to the "memory" of a perfectly decent teen movie. "10 Things I Hate About You" was actually a pretty good movie (at the top of its genre), with a great leading couple: both the characters (Kat and Patrick) and actors (Stiles and Ledger), among others, like Joseph Gordon-Levitt as Cameron; we can't say the same about this. Also all the changes in the story are for worse, in my opinion.
In comparison Cameron is ridiculous, Katherine on the verge of shameful, and Patrick, well, you know.
And I just realized that there was a 'Mandella' in the movie (didn't remember the name of that completely different character; not that this Mandella is bad)... And where the heck is Joey?? In both there is in fact a character named 'Joey Donner', but they are in NO way the same person, not by a long shot, at all. And Joey was quite crucial!
Dana Davis as Chastity (unexisting character in the movie, as Bianca *was* the popular girl, not trying to be one) is quite annoying (successfully, this is a good thing!).
Yes, the series is - obviously - entitled to be different from the movie. But it shouldn't really have the same name (doesn't make much sense now does it?), and it should definitely be better, regardless of its (lack of) similarities to the movie.
