I enjoy these films and as good as some are / not so good, I think The Conjuring Universe movies each deserve the premium treatment in a matching set.
The same goes for Insidious, and I really like the Nova release but again there is inconsistency in collections with lack of releases or lack of matching artwork.
If Nova released all of the Insidious movies then bam, there's your collection sorted. All matching, all the same retailer and all the same series. Unfortunately it's not meant to be.
Now if the Conjuring Universe became a project by Manta Lab for example then how fantastic would each release be.
There's a steelbook release out there for every Conjuring universe movie I believe but the steelbooks themselves are not so great and all over the place. The HMV versions of the first films are decent but
i'm the type to want to collect the entire universe if I did so.
