"The Walking Dead" Season 7 keeps losing people -- not just characters, but viewers.

Season 7 started very high, with 17.03 million viewers and an 8.4 rating in the 18-49 demo, then slipped to just over 12 million and a 6.1 rating for Episode 2. The past two weeks, it has had 11.72 million viewers and a 5.7 rating for Episode 3, "The Cell," then 11.40 million and 5.4 rating for the November 13 Episode 4, "Service." That most recent episode was hyped as "supersized" with an extra 25 minutes, so you'd think that might bring in more viewers. Nope.

Why?

It's possible AMC is losing a few viewers to HBO's "Westworld." Don't misunderstand -- TWD is still the biggest show out there by a lot, but it is slowly slipping in the ratings while "Westworld" slowly rises. It would take a loooooong time for "Westworld" to catch up to TWD, at least in terms of "live" Sunday at 9 p.m. viewing, since it's still only at around 1.75 million viewers and a 0.8 rating. But it's ticking upward, and the buzz from the most recent episode -- a serious game-changer -- may lead fans to rewatch the series and newbies to catch up to see what the fuss is about.Both TWD and "Westworld" pick up viewers throughout the week with delayed viewing, and "Westworld" has been making headlines for doing better in Season 1 than "Game of Thrones" did in its first season, in terms of overall viewers. It's still no match for TWD, but it's possible some fans are choosing to watch "Westworld" live and catching up on TWD later in the week, or just dropping the AMC show entirely, as they threatened to do after the Season 7 premiere.

Are you watching "The Walking Dead," "Westworld," something else, or nothing on Sundays at 9 p.m.?
