Looks like a couple of series I've been watching have wrapped up now for the season, so...
The Avengers: Earth's Mightiest Heroes (Season 1) - I made no secret at the beginning of this season that I thought this show started weak. Thankfully, after an early series of mediocre standalone episodes, the show has dramatically improved over the course of the season with multiple story arcs and some truly entertaining writing (especially with the Hulk, who is probably the show's best character and has all the best lines). It's not up there with the Justice League animated series yet and there are still some minor issues with characterization here and there (Iron Man sometimes comes off as a child, and Wasp can be annoying), but it's getting there. The season started with a wimper and ended with one of the better season finales (which may not have aired in America yet, as the final episodes just popped up on my TV Torrent site) I've seen in an animated show in years. Highly recommended, and I hope it returns for another season despite it's underwhelming ratings. Hey Disney, if you want good ratings don't stick a show on Disney XD, which few people have.
Being Human (US) - Like Avengers, this was another slow burn. I started out hating this cast and thought the writing was weak, but over the course of the short 13-episode season the show has gotten a lot better. The special effects are still goofy and the acting can be hit or miss in places, but this is a pretty solid (though not spectacular) show now with some decent writing. I look forward to this one returning next season, hopefully for a longer season.
Star Wars: The Clone Wars (Season 3) - Wow, Season 3 was extremely hit or miss. It's pretty distinctly divided into two halves: the ****ty first half where we have such riveting stories as "the droids go for a bath!" and "investigate poisoned TEA!"....and the pretty awesome second half that returns to what makes this show and Star Wars in general entertaining with epic fights and delving into the Star Wars expanded universe lore. I don't know what happened that caused this season to end up this way (especially since literally only half this season takes place after Season 2), but it really is disappointing. In the end, the number of bad episodes just about equals the number of excellent episodes for a pretty mediocre season in general. I hope the production staff at Lucasfilm have learned their lesson about making bad television in Season 3, because Season 4 is already confirmed. I just pray that Season 4 can make up for the failures of Season 3 and live up to the awesomeness of Season 2.
