Without a good pilot episode, it's an uphill battle for a TV show to succeed, as the premiere is what convinces audiences to keep watching or give up on the series. However, it's just as much of a problem if the pilot is the show's peak, using all the excitement and intrigue up in one go. All these series share a similar problem; their essential premise doesn't have an endless supply of conflicts and storylines. Many of these shows could have wrapped up after season 1, but continued past their expiration date because they were too popular to cancel.
