Show was pretty decent for season 1/2, did some things differently then the standard ER show and did them well. Season 3 had some issues but wasn't all that bad. Season 4 is just a mess. It's hitting all the negative tropes of an ER show, the story itself is all over the place and the "big event" for many of the episodes are just ludicrous. Sorry to see the series end on such a sour note.
