Unfortunately, tooooooo many folk think that the more different transitions the better. They don't see the distraction . . . until they get better at making shows. The next thing that's happening is to see how many different styles one can use in the show. That, in itself, isn't bad. What's bad is that what is often used doesn't fit the show very well and makes it hard to watch more than once. It takes awhile for the new show creator to sit back and take a gander at the show as if they were viewing it for the first time ... and from a viewer's perspective (vs the creator's perspective).
Too often the people who're learning how to create a show go more for the wow! stuff vs the stuff that's going to keep people coming back for more. It takes awhile before common sense sinks in. Well, it's often just part of the learning curve!
