Screwed by the Network: Cut Short so that the network could produce another show, past its prime days. This was so bad that Everwood fans rented a Ferris wheel outside of Dawn Ostroff's offices, attempting to help renew the show, but to no avail.
What Could Have Been: An alternate ending was filmed for the Season 4 finale, back when the producers were hoping to get renewed for a fifth season. Madison returns to Everwood, and Amy is left waiting at the Ferris wheel as Ephram meets up with his ex-girlfriend. There were several plans for Season 5, including Nina being pregnant with Jake's child, more of a focus on Delia, Nina and Andy's wedding, the return of Andy's father, and Ephram and Hannah getting together.
For the finale, there was a scene scripted, but not filmed, where a majority of the cast gets back together forty years into the future for Andy's funeral. Again, this was dropped because the producers were hoping for a fifth season.
