The MST3K was always an add-on tier in VRV. They do have a number of Rifftrax still in the VRV Selects section. They’ve been grabbing some interesting stuff including all the Stargate stuff including Origins and weird things like Freakazoid’s full run, Killjoys from SyFy and random animated movies. Considering Crunchyroll and Funimation are each $8 on their own, $10 to get both plus all the addition Mubi/Shudder/VRV/Roosterteeth stuff is pretty phenomenal. They’re also getting way better at offering cross service suggestions. So if you a certain Anime it will suggest similar themed content across all the verticals in the app now.
Hulu does have a decent selection. I’ve also been thinking about getting a HiDive sub recently. They’ve added some interesting older shows, but they don’t seem to have apps for Roku or PS4 which is kinda a dealbreaker.
