I'm definitely interested in all of these. I never got round to picking up BU's Night Train Murders either, so I'll probably go with the UK release now.
Spasmo is a fun little Giallo. I like it, anyway, so I'll grab that on Blu for sure. Shows that Lenzi is more than just a cannibal man. I'm still hoping for Seven Blood Stained Orchids and Eyeball in HD too.
Bloodstained Shadow is a no-brainer. A fantastic Giallo.
