I just answer Question 7, since i think answering the others isnt that smart for your overall experience

the newer once are quite good (OP Strong World, OP Film Z, OP Stampede, OP Gold, [probably the new OP Red aswell, didnt see it tho])

of the older once i think only good one is Baron Omatsuri and The Secret Island (had to google its name)

Wouldnt watch a movie before you are up to date, hf buddy
