Happy Holidays! With plenty of folks traveling and spending time with family — or gearing up to watch college football games — a whole lot of shows remain on hiatus this week. But there are still a few gems to check out, including some deep-cut genre movies.

The big story this week is the Season 2 premiere of Fox's Trek-esque action-comedy-drama The Orville. Yeah, this show is a lot. The first season started off rough, but by the end of the year it really found its stride. It has a ton of heart and a lot of laughs. Here's hoping Season 2 keeps things going in the right direction. This week also brings the season finales of Z Nation and Van Helsing on SYFY. ABC also has a special event celebrating Mickey Mouse's 90th anniversary.

There are also some holiday stalwarts, such as The Grinch, Happy New Year, Charlie Brown, Elf, and a few others. As far as general new episodes, NBC is dropping a fresh Midnight, Texas, STARZ has new episodes of Counterpart and Outlander, and there are a few others lingering around.

Check out our full rundown below and let us know what you think.
