these careers are flatlining! get me a show to put them on, STAT!

I used to watch ER, back in the day. You know, when it was the hot new show, right after Seinfeld? But I haven't seen a single episode or ad for it in probably 5 years now. I accidently flipped to it last night and found that these people are now in the cast:

the girl from 3rd Rock from the Sun,the guy from A Walk to Remember,

and John Leguizamo (yes, he also played Luigi in the Super Mario Bros movie).

What the heck has happened to this show? Is it now just a random collection of sort-of-famous people? What's the over/under on episodes until Jason Priestley shows up as a chief surgeon? Needless to say, my desire to watch the show hasn't increased. My heart still belongs to another...
