You can ban shows from appearing on your Front Page. To ban a show, while on the Front Page, tap the episode name and more details will display. There’s a small red icon at the bottom right that looks like a "NO" symbol. Tap this to ban a show from your Front Page.
To undo a ban, go to the app’s Settings > General > Front Page to view a list of shows you’ve banned. Tap a show in this list to un-ban it.
