It's a choir. Just watch the first season. It's not worth your time watching the rest, unless you like watching great shows go bad.
I think it's a watchable show for the most part throughout, but it's just not a very good show and not anywhere near the quality of the first season.
For what it's worth, I thought the final season was the series in a microcosm. It started off decently strong before going completely off the rails.
My view on watching only the first season is more a statement that it's better to just watch the first and stop than it is to watch only parts of the first.
