The only title on this list that had a wait status in May is Forgotten Silver, which was Long Wait then. I haven't experienced any actual wait times for any movies, because none of them was at the top of my queue. There are 490 titles in my queue (which you can see on Listology, so if these indicators are accurate, there are about 10% waiting.

The Sentinel (Very Long Wait & Out of Print)
