Here are (my) 10 reasons why Ugly Betty shouldn't be and may I add also, doesn't deserve to be cancelled in no particular order:
1) It is one of the few shows which has a worldwide fan base as big as it has already- from the US to the likes of Australia, UK, South Africa, China to name Ugly Betty's appeal is massive.
2) Despite falling ratings for season 3, and criticisms from some ex- Ugly Betty fans, most notably from the Benry and Getty quarters, it is actually a definite improvement over season 2, of which I didn't have much hope for, the longer it went on.
3)It is the only show I tune into on a regular basis; there hasn't been a show that has gripped me and appealed to me more, since Caroline in the city as I was a fan of that show beforehand
4) Two words: marc and amanda- perfectly played by michael urie and becki newton.
5) I cannot think of a better cast of actors than the ones we have on this show to play the likes of betty, daniel, marc, amanda, christina and willie than in america, eric, michael, becki, ashley and vanessa.
