Primetime heavyweights like How I Met Your Mother, Glee and Parks and Recreation do not have anything to worry about when it comes to ratings.

These shows have a loyal fandoms that watch, comment and even tweet all at the same time every week in record numbers.

Comedy newcomers like The New Normal and The Mindy Project started the fall television season with enough momentum and star power that the success and the laughs came very quickly. Yet, not all TV shows are so lucky.

Some were doomed from the start due to bad show titles, awkward casting or played out plots.

Others start off with so much promise and Emmy buzz, but  end up pulling a Pan Am and become a major disappointment.

It seems like half-hour series are the worst this year with comedy after comedy being an epic fail.

ABC better give thanks to its golden ticket Modern Family because if it wasn’t on the lineup, the fall comedy shows on the network would be embarrassing.

Watch the following shows at your own risk. Prepare for bad 90s humor, awkward audience laughing tracks and acting that makes Kristen Stewart look like Meryl Streep.

666 Park Avenue ABC – Sundays @ 9 p.m.

If at first you don’t succeed, try, try again? Well, if this show was supposed to be ABC’s answer to “American Horror Story,” then they should go back to the drawing board. It is sad that after the success of Ugly Betty, Vanessa Williams has attached herself to this train wreck. Despite the “666” title, this show is not scary. It is a far cry from The Walking Dead  or even The Twilight Zone.

Partners CBS – Mondays @ 7:30 p.m.

Another Ugly Betty star fell victim of being linked to a horrible show. Michael Urie plays a Jack-like character from Will & Grace fame, who is best friends and business “partners” with a heterosexual male. The dry gay-straight humor begins! Partners is not like The New Normal. This show would have maybe been funny in the 90s, but in 2012 the jokes are ridiculous and the chemistry between the cast is lacking.

Emily Owens, M.D. CW – Tuesdays @ 8 p.m.

The CW is on life support and has been for a couple years. The demographics, and most importantly the ratings, just aren’t there anymore. The network is surviving solely because of the intense love of Gossip Girl, which is on its series finale, and Vampire Diaries.  This show stars an unknown Mamie Gummer who plays Emily, a first-year medical intern who is trying to find her way in a medical hospital that the show portrays to be exactly like high school. This medical drama won’t be the new Grey’s Anatomy. Give this show a few weeks and it’ll be another show on the long list of cancelled flops.

Ben & Kate FOX – Tuesdays @ 7:30 p.m.

Why? Why? Why must this show be such a disappointment? It had such a promising pilot episode. It was funny and refreshing. Now, as the season goes on and the hype over the show decreases, it leaves fans wondering if it will get better. This brother–sister comedy had so much potential, but the laughs and charm of the show just isn’t transferring. It does have the ideal time slot of FOX’s comedy Tuesday with Raising Hope, The Mindy Project and the show that shouldn’t be on air, New Girl. Here’s to hoping this show makes a 2007 Britney Spears-like comeback!

Nashville ABC – Wednesdays @ 9 p.m.

Dear ABC, thank you for creating a TV version of “Country Strong.” – said no one. Not only has Hayden Panettiere not been relevant for anything other than her good looks since Remember the Titans (sorry, but who remembers Heroes?), but this Reba McEntire-type singer versus a Taylor Swift-type singer didn’t work for Gwyneth Paltrow and it’s not working in this show. Get it off my TV screen STAT!
