Hi every one
the answer is : think , beacuse when you say i think a move is good
here you didn't said the time but when you say i'm thinking that mean
that don't see the move yet.
Hi!
I voted for "I think the film's good". But I believe it is possible to use both case due "I think" is a present simple and "I am thinking" a present progressive. So "I think" it can be undestanding as an opinion, and "I am thinking" is an extended action.
it should be mentioned that ''I am thinking'' in this case(to have an opinion) isn't very natural other than in some colloq cases as it serves as a stative verb which can't be used in continuous form.
