Use original title from the source. Though in this case that "I'm Ok With That" part can be cut off just to keep opinion out of the title as well as to ensure the title is short enough to actually fit.

Please don't create new tags for a mere mistake in already established tags. http://filmwatch.com/user/blogpost/_jl_/515923 In a case like this just use the Spy Kids 4 tag that's already there (Just has the wrong subtitle) and PM me and I can change to the corrected official title. Thank you.
