Why are you looking at TV Show files in Windows Explorer, and in thumbnails view?
Use MC to view and manage your TV Shows. Then you won't need to see that mess. Or if you really need to look in the directories, use the Details view. But you shouldn't need to regularly look in those directories, or manage the files using Windows Explorer.
Of course, if you must, you could just select the Sidecar files and hide them, using Windows Explorer.
