No shit lol
Yes, if you give this as "Poroshenko recently forbid all films that paint a positive picture of Russia.":
1.
'Poroshenko recently forbid' - no, changes to the law were issued and voted by Parliament, so literally they forbad it, not him; POP just signed to make it works
2.
'all films that paint a positive picture of' - again no, prohibition relates only to the films and tv-series "which contains popularization, agitation, propaganda etc. of the any actions of law enforcement, armed forces and other armed, military or security forces of a state-occupier" - so only to the some part from all the amount of films.
3.
'Russia' - there isn't a single word 'Russia' in the text of law, however it presents in explanatory note why such changes should be voted, and since Russia is recognized as occupier - yes, their films become prohibited by this changes. Although this changes isn't especially anti-russian inherently (if we recognize f.e. USA as occupier, their films will become forbidden too) - it intended to protect our information environment, so all is ok with this changes.
