Questions left unanswered at the end of Season 3 of Damages

Season 3 of "Damages" does keep you watching and totally intent right up to the last moment but then, ultimately, is it a great series? For entertainment, certainly; for acting, Glenn Close is a force of nature, powerful and dominating, and Rose Byrne is maturing as an actor season by season; and many of the secondary characters - notably Lillie Tomlin, Ted Danson, and Martin Short - each primarily known as comic actors, give some of the best dramatic performances of their lives. And yet - by the end I still feel that not all the questions of the extremely complex plot were answered, not all the answers were really credible, and there are far too many loose ends, false leads, and red herrings - it definitely has the sense of something that the writing crew was building as it ran along the tracks. The 3rd season takes on a family obviously modeled on the Madoffs, but in this case the son, instead of being a hapless suicide, takes over the family enterprise and tries to access the money that dad had sheltered. In opposition, Patti Hewes (Close) tires to access the money as well to make whole those who'd lost their fortunes in the Ponzi scheme. Where this season becomes a little weaker than the first two is in that Patti plays a less central role, we don't see her wiles, smarts, and ruthlessness at work in service of her clients - most of the dirty work is done by Ellen (Byrne) and Tom (Tate Donovan). Patti's animus isn't so much against the malefactors as against the older woman who's ensnared her son, and these scenes are not too well developed and they end kind of abruptly. Lots of scenes in which Patti tries to recollect a memory of her youth regarding her first pregnancy - mysterious in a way, but a bit distracting from the main line of the plot. Lots of business about a stolen purse and a car crash in which the driver takes off - all answered, more or less, at the end. But who was this architect stalking Patti? And who was the British assistant that she fired - and why did she do so? And why is Ted Danson even in this season? And, and ... Well, overall, it's a totally fun series, especially if you can forgive a few ragged threads at the end - this is a patchwork quilt of a series, not a Swiss watch.
