boring and unoriginal
trite - banal
Something, such as an idea, story, or remark that has been said or told too many times can be called ‘trite’. Such overuse tends to lead to apathy and a degree of hostility from those on the receiving end. For that reason, this word is used to express strong disapproval.

The movie was tedious and totally lacking in originality. How can they keep churning out such tritely formulaic garbage?
