The Deadly Spawn is a real disappointment because we were shown an image of the "new transfer" early on and it looked amazing. Then we got the Blu-ray and it looked worse than the Synapse DVD. So they recalled it and months later we got a "new" Blu-ray that only looked about as good as the Synapse DVD. Then they said TS. What a hot steaming mess that all was.
Hammer's Blu-ray releases of Curse of Frankenstein, The Devil Rides Out and even Horror of Dracula to some extent have all been disappointments. The Brides of Dracula has been another as well: http://www.youtube.com/watch?v=NgtqEU-Z5hM
