Always make sure it is possible to skip the times not worth watching.
On this page I discuss the importance of having characters who have lives beyond what you see of them.
I once employed a cast of characters - actually, caricatures
would be more appropriate - whom I called the Comic Five. I remember them for all the wrong reasons now. Among their worst offenses was hogging the attention of my audience as if their lives depended on it - which it might seem they did, as they were as if they were born the day my strip started and did not exist at all when not being seen.
Now, some of the things I mean by that. They could only say something had happened to them if it had been shown in the strip. They filled the strip with things that they evidently did because they thought they had to, not because they wanted to (notably including their dispassionate parodies). They regularly tried too hard to be funny, and consequently failed.
Eventually the superior counterparts to the Five, the Black Pearl Crew took over.
A good reflection of how they are an improvement is Still We Fight.
The viewpoint of that parody has the luxury of figuring out what does not suit him, as well as a confidence in his own survival that the Five never had. Also, a less obvious sign that the parody is not desperate for attention is that it does not make references to anything relevant to particular audiences. (The Five were notorious for pandering to my readers, due to their need for those exact individuals and their lack of knowledge about anyone else.)
