It's true the the Twilight saga wasn't that great, however you cannot blame the actors (Except Stewart) for the crappy quality of the movie. Twilight has a horrible premise and not even the greatest actors on the planet could fix it. Hell, It's so bad it couldn't even make a decent comedy.
A lot of people bad-mouth Robert Pattinson saying that he's a terrible actor because he was in Twilight. But Robert Pattinson was in another movie franchise, and for the short time he was in it he did an awesome job
Harry Potter and the Goblet of Fire - Cedric Diggory
As I just said he did an AWESOME job playing Cedric Diggory. I think that Robert Pattinson could do become an even better actor if given the opportunity to be an a great movie like Harry Potter again. I heard he's playing a character by the name "Negan" in The Walking Dead soon, and I expect him to do great!
