I think that is the easiest way to explain this drama concisely. It's a cult classic. If you read some of the critical reviews, I'd tend to agree with them, but the thing is it's what makes it a cult classic in my opinion.
The acting isn't perfect and the dialogue can be weird at times, but that makes it even funnier.
I think if you go in knowing it's not a serious tv show, you will better be able to enjoy it. You can't compare it to highly choreographed big budget tv shows of today because that's not what it is. But if you go in and just accept it for what it is, a lower budget old funny spoof on some cliches, I think it's pretty solid and has pretty good rewatch value
