I think Season 4 was definitely D.H.'s peak, but Season 5 was pretty amazing too.I loved seeing Gabrielle outside her comfort zone, with the extra weight, rowdy kids & poverty.
Season 6 was the only season i can call truly "shit" though.The storyline with the terrorist neighbours was so weak.Isn't this the season where Katherine turned into a lesbian? How convenient.
Season 7, i think, was pretty decent.It started off amazingly, got a little redundant in the middle, but in the end it managed to pull itself together.
Gabby's obsession with dolls was such a cringeworthy moment though.
