As always, possible ***Spoilers*** below.
Once Upon a Time
It was nice to see Winn have more to do. I really like Jeremy Jordan, and I like his character. I think Katie McGrath was a great addition to the cast as Lena Luthor, and I like the direction they've taken her character. I just hope they don't have her character go the way of McGrath's character in Merlin after a few seasons. It was also great that we got to meet Superman. I just wish that he had been in more episodes. We'll see if we'll get more of him in season 3.
When Cat Grant showed up at the end of this season after being gone through most of the season, it was almost as good as when a certain person (I won't say who, because **spoilers**) shows up on Buffy, the Vampire Slayer at the end of season 6. Sometimes you don't know how much you miss a character who has left a series until they show up again, and suddenly, you cheer when you see them again.
Jane the Virgin
Agents of S.H.I.E.L.D.
This remains one of my favorite shows, and I'm so glad that it was renewed even though the ratings aren't that great. I wish people who stopped watching during its rocky first season would come back and see what a great show it's become.
The Big Bang Theory
Legends of Tomorrow
Sleepy Hollow ended this season, and I have to admit that I kept watching this show just for Tom Mison (see above picture). The series wasn't the same without Nicole Beharie, and fans really felt her absence. Even though the show wasn't great after the first season, the chemistry between Mison and Beharie was so good that it kept some people watching, including myself. With Abbie Mills gone, they had to find another "witness," and I thought that making the new witness a young girl was an interesting choice, but I feel they could have done so much more with that than they did. Regardless of the things they did wrong with this series, Ichabod Crane was just so darn likeable, that it was hard to dislike the show completely. Now, I hope that Tom Mison is cast in another American series playing another great character, just because I don't want him to fade away into British television where I might not see him again. I looked on IMDB.com, and I didn't see that he has anything in works (in film or television). *sob*
Grimm is over. *sob* This has been one of my favorite shows, and even though the series has had its ups and downs, I really enjoyed the characters. I felt like the finale had a lot of plot holes. I just kept getting angrier and angrier as more characters died, and I thought that the ending was a bit of a cop-out, but I guess they really wanted to go out with a bang. I do have to say that I wouldn't really like to see a series that follows Kelly and Diana and the triplets.
