Bro, probably you should re-state your query on the 'Subject' field to avoid confusion.
Kse right now it could be read straight up as...
"Is it worth collecting old movies that,
u have already watched in Bluray?"
...meaning the titles you already watched in Bluray, are you still gonna collect it?
If you change the syntax to:
"Is it worth getting in Bluray, old movies that you have already watched?"
...then you'll probably better drive home your point.
...if this was your original intention then my answer would be...
Y E S Cheers buddy!
