The specter of an infinitely superior predecessor also haunts the new comedy "Bachelorette," a wan "Bridesmaids" wannabe. I recently re-watched "Bridesmaids" (and the other comedy on my 2011 top-ten list, "Carnage"). Just as funny the second time, and Melissa McCarthy's role remains one of the freshest and most original comic characters in memory. There's nothing of that caliber in "Bachelorette," though it does contain a few chuckles and a couple of scattered laughs. Rebel Wilson, Kristen Wiig's skin-crawling roommate in "Bridesmaids," plays the bride here, but Kirsten Dunst gets the lead as her ultra-competent, type-A maid of honor.
