re: Grey's Anatomy season 5
Much better then I expected. For those that like shipper type shows, they've already started off with some interesting ones.
Grey & Derrick are still an item, of course
Alex & Izzie can't get it together.
George.. will he ever figure out that Lexie loves him?
Torres & Hahn... this is the one I thought was pretty dissappointing. They are now contending that Hahn has just now come to discover she's gay. This is an almost amnesia moment from how she was setup previously. Maybe I'm wrong, but it was always portrayed like she "knew" she was last year; so her saying "I'm a virgin to this" seemed off-tone.
Christina & Iraqi military guy: goofball. How did he get a run of the hospital and was able to practice so quickly without anyone checking on him or looking up his credentials. Might as well been some poser off the streets "oh well, let him practice". Storyline I liked least, even though I love the actor.
I like the concept that Seattle Grace is now a hospital on hard times, bad reviews, whatever. I think that could be interesting. I also liked them finally pointing out something I thought was obvious the last two seasons.. everyone went straight to specialties and there were almost no generic surgeries for them to use to learn. I mean, maybe an appendecitis isn't the ratings draw of a double-impaling, but I think several episodes focused on them getting a lot of time doing practical procedures would give the show medical movement and allow them to build the characters too.
Considering the repeated explosions, etc. in their hospital, I'd avoid it too

Regarding the episode in two weeks:
Warning: Spoiler! (Click to show)
Looks like a water disaster in two weeks. Ok, I've worked in a medical facility. Most codes require the floors be steel tensioned concrete. So, when they showed a water leak crashing through the ceiling from above I thought: what kind of wood structure hospital is this?????
