Since it's on NBC, it will do bad and eventually get canceled, but I've been looking forward to this show all season. I like Glee, so no, I hope it doesn't destroy it. Both can coexist.
Lets get into this. Smash has Katharine McPhee (who is incredible), Megan Hilty (an excellent Broadyway actress), Brian D'Arcy James (another excellent Broadway actor, who was Shrek in Shrek the Musical) and the epic Angelica Houston.
The fact is, Glee is an auto-tuned pit. None of that cast besides Lea or Amber are actually talented live, and they edit everyone's voices in the studio to the MAX, plus its extremely cheesy, tired and just bad.
Smash has tons of great producers, Broadway composers are writing the ORIGINAL score, Speilberg is producing and the cast is excellent.
In accordance with his modus operandi, Ryan Murphy was obligated destroyed Glee sometime in season 2 or 3. Smash won't have to try very hard to outshine the competition.
I know that Katharine has already smashed Lea in terms of vocals, beauty, talent and presence.
So obviously her show will do the same.
Lies lies lies.
Maybe the only thing Katherine has over Lea is beauty, but Lea still looked more unique and beautiful in her own way.
about vocals, talent,presence Lea will leave Katherine in dust especially vocal and acting, i wanna see Katherine do My man, Dont rain on my parade lol.
It is awful 
and also there are meant to be 15 episodes. I'm ready
