You should go and see the film. You ... it.

[Grablevskij]

English grammar in use by Raymond Murphy. Second edition.

Unit 40.

Ex. 40.1 Complete the sentences using would + one of the following verbs in the correct form.


2) You should go and see the film. You ... it.

I decided that would is inappropriate here.
My answer was: "You will enjoy it".

First of all, there was no such pattern in the theoretical part. Please, have a look at the attached images (3 pieces).
Secondly, will denotes predition. It suits here.

Could you comment on it?

 

[5jj]

Both will and would are possible:

You will/'ll enjoy it (if you go).
You would/'d enjoy it (if you went).

 

[Charlie Bernstein]

Either way is grammatical. Yours is more emphatic, less tentative. I like your way better.
