Film Critic has a lot in common with Clot for me. It's a card that directly counters a number of decks when it hits the board, turning entire strategies on their head. It's also a card that, simply by existing, changes the meta. It doesn't actually matter all that much if you're running Film Critic. It matters that Film Critic exists, and that some people are running it. It means that people who are building corp decks built primarily to take advantage of on Access abilities have to either abandon those decks entirely (as it was expected would happen with Fast Advance), or remove tertiary pieces of those decks to include things like Snatch and Grab or Contract Killer to answer people who are using Film Critic.
Film Critic has the upside that it addresses a number of the most popular Corp decks in the meta that aren't Fast Advance - Butchershop can't affect you if you don't steal any agendas. RP's self-protecting agendas like The Future Perfect become far less safe. NAPD Contract's ability to hide from Runners with less than 4 credits is gone. Even Fast Advance suffers a bit, as NAPD looses the ability to be a "safe" or tempo destroying install.
However, it suffers from the fact that it can only be found by drawing, or by using Hostage, which is reasonably rare. Street Peddler can help if you get a good draw, and has the same "Surprise! I can deal with you!" quality. It's also a resource, which means decks that want you tagged only have to ensure they have a way to tag you that isn't based on agendas and it's turned off.
But to go back to the beginning - that's not really the point. The point is that it exists. And at 1 influence, it's potentially in every deck out there.
