I was a huge GLEE fan during its first season - and Cory Moneith was definitely one of the most promising newcomers within its cast. A devestating tragedy that he is no longer with us.
Same here, although I lasted a couple of episodes into its second season before giving up on it. Even though the writers often decided to unnecessarily make his character into a jerk, Monteith was always a major pillar of the show and they won't be able to replace him.
It'll be interesting to see how (or even if) they decide to carry on. The decision to, for all intents and purposes, fire the bulk of the original cast looks even more foolish now. A new season with the old cast could have provided a way for the show to move beyond the tragedy. Now, with a largely new cast, I don't see how they're going to pull it off, given that it's one of the worst-written shows on TV today and one that is carried entirely by the talent of its cast.
