The bigger problem for me (beyond the lack of chemistry of any of the players) was the combination of terrible writing and worse acting. The writing staff apparently didn't believe in either subtext or subtlety, driving home every character beat by having someone say the equivalent of "You know something about you? You're (fill in the perfectly obvious trait). I found Raymond Lee, Nanrisa Lee, and Ernie Hudson to be okay, but Caitlin Bassett and Mason Alexander Park were working at the level of mediocre high-school thespians.
Somehow, the original staff told us everything we needed to know about Sam and Al without driving it home with a sledgehammer, which was something the new people never figured out.
I won't miss it, though I do wish they'd have brought Sam back. (I guess Bakula was too smart to get mixed up with this one.)
