The problem with that is that not everybody knows what a wormhole is and how they (more or less) works. Sure, a good percentage of movie viewers have seen this explanation countless times, but there's a whole bunch of people who haven't for any number of reasons. So directors and screenwriters add those scenes so that people who are new to the concept of wormholes won't be lost.The only less-accurate way to explain a wormhole (than the folded paper) is all the other ways of explaining it in 20 seconds.
Having said that, wormholes have been used/covered often enough in Hollywood that I think they could just skip the explanations from now on. People get it. It's a magic hole that you can unlock with (insert big technical challenge here) that teleports you to some other place/time. It takes you to Narnia, or back in time, or to JCPenny's, or wherever you need to go. There's a way to rationalize it with current science.
