Not everyone is gleeful about Glee. Slash, the rock guitarist of the Guns ‘n’ Roses fame is very clear about his dislike of the Fox show which is attracting all the big names in the musical and movie industry to put in an appearance.

In an Interview with EW.com, the rock guitarist did not think the band would ever agree to a Guns ‘n’ Roses tracks being covered on the show. He said that they had already turned down a request before.

Elaborating on his dislike he said, Actually, I look at Grease now and think 'between High School Musical and Glee, Grease was a brilliant work of art.' He added In the current climate of what’s going on in entertainment these days, I try to be more optimistic than negative because it’s really easy to get negative about it, but I draw the line at Glee. Glee is worse than Grease and Grease is bad enough. “

With Glee being one of the most popular shows running , it is difficult to imagine any artist or band turning down an appearance offer but there are some who are still holding out. Bryan Adams is one of them. King of Leons, the rock band, is another. Coldplayinitially held out but caved in later. Maybe the popularity of the show in the US got to them.

Writer-producer Ryan Murphy recently claimed, only two artists had ever turned Glee down for song rights, and one of those did a turn-about. My favorite rejection was Bryan Adams, Murphy said, at the Emmy Comedy Showrunners Roundtable in June. Coldplay and Bryan Adams were really the only rejections. But Coldplay called later and said, 'We're sorry, you can have our catalog.'

The critics of the show are out there and many. Generally the grouses are; the musical kills the original for the lovers of the music, why do they not have original music and as one critic put it, “ Can someone tell me how the show has had so many hit singles? Do people love show-choir covers of pop songs that much?

The popularity and sales figures show that, maybe, they do.
