I think this last episode exhausted my (considerable) patience with this show. I waited for it to find its footing, but it's just sinking into quicksand!
Forget that the tired cliche of a plot (good guy must protect bad African dictator from assassination attempt) would work just as well to set up a skit on "Whose Line is it Anyway?". Forget that they're trying to introduce characters who are separated at birth from the daughter from Gilmore Girls and Xander from Buffy.
You know your show is in trouble when the viewers start nitpicking the lighting. The stock tech geek guy looked like he was wearing fluorescent lip gloss in his scenes. Isiah Washington's big death scene (oops, sorry, spoiler) was overshadowed by all the weird glare that made it look like one eye was still open after he was dead. Did the writers call in some pre-strike favours from the gaffers?
