'The very one' is out of place here. There is only one use I can think of for this, and here are a couple of examples:
"I'm so angry with myself for losing my watch - I've searched everywhere for it."
"I found this under the table yesterday - could it be yours?"
"Yes, it's the very one!"
"We need somebody special to talk at the Book Club annual dinner next month. Any ideas?"
"How about John Mortimer - good stories, a good speaker and he lives nearby."
"I think he'd be the very person."
So 'the very one' means 'exactly the right one'. The important part is 'the very', which can be followed by various words, according to the context - one, thing, person, answer, etc.
Check your verbs. Many films were shown last year. Triple Trap was one of the most interesting. Therefore 'TT was one of the most interesting films that were shown last year'. I hope that looks good to you. It does to me!
