As of the 2nd episode, Alanna Masterson (Tara), Josh McDermitt (Eugene), and Christian Serratos (Rosita) have been promoted to opening credits billing, replacing Steven Yuen and Michael Cudlitz, while Tom Payne (Jesus), Xander Berkeley (Gregory) and Khary Payton (Ezekiel) have been promoted to series regulars ("Also Starring").
2nd episode was dull because it was a jarring change from the previous episode--this was actually supposed to be the 3rd episode, but AMC switched it with the 2nd episode, which features Daryl, Negan, and Dwight.
Shiva is actually impressive though, considering it's not a real tiger, but a mix of CGI and animatronics, which is probably costing more than the actor's salaries, heh.
