You will enjoy Cheers unless you are very young, in which case, it might not be your brand of humor. It is a sitcom in the truest sense and very, very good at what it is supposed to be. A true classic.
At least give the first five or so episodes a shot.
About 2 or 3 years ago I tried the same endeavor, so run through Cheers all the way. I made it almost through the first season and just kinda gave up on it. I'm not trashing it, it just wasn't my cup of tea. To be fair though, I didn't have anyone to watch it with and didn't have netflix, so I had to watch it in my room on my laptop whenever I did watch it. Not really the best viewing conditions.
Part of Cheers success is that they didn't rely on their charter characters for the entire season. Coach dies and they bring in Woody. Diane leaves and they bring in Miss Howe and Frazier. They were solid with their replacement program.
I did something similar. I watched the entire series of Frasier on netflix. Took me a couple of months. Talk about a show that has held up extremely well. I would imagine Cheers is the same. I love the idea of taking a classic sitcom and running through the whole thing.
