“The Bachelorette” is shaking things up this season: Instead of having a former “Bachelor” contestant as the lead, as has been the case for all past seasons, it has dipped into another reality show’s cast. Taylor Frankie Paul, from “Secret Lives of Mormon Wives,” is taking her turn at dating 25 men from different backgrounds, which she hopes will help her finally get over her ex, the father of her son. Some “Mormon Wives” fans are excited to see Paul bring her self-proclaimed messiness onto to the comparatively buttoned-up “Bachelorette.” Either way, I am sure we will enjoy the journey. Sunday at 8 p.m. on ABC and streaming the next day on Hulu.
