There are two types of bands: Serious and not serious.
A serious band is like a professional sports team. They practice practice practice. Sometimes practice is not fun and is more like work. But they get better.
A not serious band is like a group of guys playing sandlot football. They drink a few beers and toss the bass around. If they get better it is a complete accident. But they have fun.
I have been in both bands and they both have their advantages and disadvantages.
One band I was in started out fun but I got tired of the lack of discipline/leadership. They goofed around and never got any better. It was fun but I soon got tired of playing simple songs poorly, so I quit. I saw them years later and they were still making the same stupid mistakes they were making when I was with them. They get a few gigs but could actually get more if they worked at getting better.
So it all depends on what YOU want to get out of the band. In my case I wanted to try different music and challenge myself to grow musically.
Actually we are working and improving, we play the tune seriously, with the intention of playing them right.
It's just that the guys are just goofy and have that "whatever happens" attitude, which I think is fun.
As for it being "horrible" maybe I use too strong of a word. Horrible is a band full of drama, something that some know I have been involved in a few times recently
