(Not going to mention those mentioned in other threads, such as The Carbonaro Effect and Leah's Scientology on CU+.)
True Detective S3E1 arrived on CU.
May I suggest also mentioning what you're hoping for that hasn't yet arrived. Then those willing can at least mention if they've seen they're on CU+ instead.
If adopted, I suggest waiting at least 24 hours before wondering about them out loud.
(Those who don't know - it is possible for a series to appear to start on CU+ but then get moved to CU shortly afterwards, usually caused by delays in broadcasting the CU option.)
Given that MC does not care, I will post new series that are currently appearing on my CU list.
Last night the following loaded:
This is Us
Death in Paradise
This is not complete, but more dependant on what I watch. Please feel free to add....
