1. Gilligan's Island

This is no laughing matter. Studios have been trying to make a Gilligan's Island reboot for a few years now. But just sit right back, and you'll hear a tale of why this isn't okay!

First off, the original cast not only played these characters during the original series, but for decades after in specials and TV movies. Second, the cast really treasured their characters. For instance, Bob Denver consistently wore a bucket hat; Alan Hale, Jr., opened a shrimp restaurant and greeted customers as the Skipper; and Dawn Wells is still drinking from coconuts! Please, Hollywood, leave this classic sitcom alone. 

2. I Love Lucy

We love Lucy, but we hate the idea of a revival. It's impossible to find an actress who exuded the same wit, charm and physical comedy skills that Lucille Ball had during the making of the classic sitcom. Although it's easy to remake the formula of I Love Lucy, it would be a crime to make a carbon copy featuring second-rate versions of the Ricardos and the Mertzes. Any studio who would attempt to make a reboot would have some 'splaining to do!

3. The Brady Bunch

Was The Brady Bunch a completely original masterpiece? No. But it gained an exuberant fan base thanks to the charm of the cast, wholesome plots and generous syndication deals. The 1990s movies were more parodies, and we're okay with that. Everyone has a favorite child or a favorite parent, meaning everyone would be hurt to see them replaced in a new series. Also, we really treasure the simple story lines the original series had. If The Brady Bunch were on today, we'd put money on the fact that producers would want to push the envelope. 

4. Happy Days

Despite the song, happy days are not here again. Happy Days should stay in the 1970s and 1980s where it belongs. Could you imagine another actor playing the Fonz? Ridiculous! Let's honor the late Garry Marshall by keeping Happy Days in the past. 

5. M*A*S*H

Out of all the shows on this list, M*A*S*H seems in the most danger of being revived. Think about it: an iconic show with an ensemble cast that lasted 11 seasons in the 1970s and 1980s. On top of that, the show was based on a movie which was based on a novel. Someone needs to put the 4077th on lock down, because we don't want to see a new version of this show anytime soon. 

6. All in the Family

One of the best things about All in the Family was that it was cutting-edge during the time it aired. The sitcom tackled sexism and racism like no others had — and few others have since. If the networks decided to bring back All in the Family, it would make little sense in today's context. It would try too hard to be a groundbreaking show, when sometimes a groundbreaking show doesn't need to try so hard at all.

7. Columbo

In reality, Columbo has only been off the air for a little over a decade. After the show ended in 1978, the series was revived for periodic specials and movies until 2003. But don't let that fool you. Studios will take anything and remake it into something new. Unfortunately, Peter Falk passed away in 2011, meaning another actor would have to portray the homicide detective. That's unthinkable. We would rather not see Columbo turn into a flashy procedural drama, thank you very much. 

8. Cheers

Just like M*A*S*H, this bar comedy from the 1980s is a prime target for an ill-fated revival. It's an ensemble comedy that ran for over a decade starting in the 1980s and still has a large following today. Also, alcohol is involved. Need we say more? Cheers is a place where everyone knows your name, but that doesn't mean we want to meet new people with a revival.
