opinion on the musical episode! whats your?? (please answer)

personally, i think this whole thing is gonna turn out bad. it like gonna be a diseaster. i wouldn't even compare it to glee. as bad as glee was this season (but improving). this sounds way tackier. because glee is slighty madami comedic, and the song can fit into the storyline easily, and the ipakita is quite light hearted. which unlike greys, is madami serious. it becomes madami like High school musical. every time i think of this episode, i think of meredith walking down the halls, pag-awit a song with a tune "gotta go my own way" (in hsm 2). which is just terrible. i'm not saying she cant sing, granted i have never heard any of them sing. but what i mean, it sounds so tacky, cliche and cheesy. like grey has such an intense and fanatic storyline, which is a bunch of doctors in messy pag-ibig triangles in a hospital. what are they gonna do. chart and then all of a sudden break into song??? or in the middle when the reattach and arm successfully, shout out for joy and sing about it?? i mean seriously?? from my perspective, this sounds really bad. and from what i can see, these thing normally dont turn out so well. mayb i'm too pessimistic. i mean, could someone give me a reason to be psych about this episode?? and do u agree? cos i need a reason badly. i really pag-ibig this show.. and this just so far sounds bad.
