Note: My spelling of some of the names below is horrendous and I don't particularly care at the moment and am not going to look them up ;-).
One show I find I'm LOVING [to the point of spending my bday money to purchase 3 seasons of] is NCIS. The cast works SO well together IMO. I'm sure there are those who would disagree and there's no REAL romantic storylines between the leads but the whole cast really works so well together. The DVD commentaries are some of the best I've heard [two actors/whoever sitting in a studio watching, calling another actor on the cell phone to pick on him about a scene [I think - maybe they just talked about it], rather than the ones like say "Friends" where it's 3 producers recording at different times etc.].
Michael Weatherly [Tony DiNizzo] is hilarious and Pauley Perrette [Abby Sciuto] is FANTASTIC and pulls off the Goth forensic scientist like nobody's business. The only regular I'm only so/so on is the Director of NCIS whose name is escaping me at the moment [character's first name is Jen]. Mark Harmon as Leroy Jethro Gibbs is just perfect. Cote de Pablo is fabulous as the Mossad agent on loan to NCIS [Ziva David] and her problems with English idioms are always good for a giggle [though none are coming to me at the moment of course - okay quick Google search: "beating around the tree", "you look like you've seen a goat", "the poor girl's probably passed on [meant passed out/tired]", "Spic and spam", "shooting fish in a pond", "pork-u-pig [porcupine]", "Does a bear sit in the woods?", etc.]
As for the romantic part... chemistry doesn't have to be romantic. There is some romance on the show, but it tends to focus on the crime fighting aspects of NCIS life. It is MUCH better than CSI, imvho, no comparison.
It's funny but smart funny for the most part. Sure there's the stuff that you would also find in something like Friends where the comedy is blatant and doesn't require a whole lot of thought most of the time or like... the Simpsons? where it's just crass [at least the last few I watched].
Okay - I need to be writing or pass out, one of the two...
