And on a serious note: if you dish out propaganda more subtly, it may be more effective in the long run. The best advertising is done without the recipient noticing it to be advertising. That is - for example - how effective Social Media Marketing works: you do not advertise to customers via social media - you engage with an audience using interesting stories.

Having your "ideology" woven discreetly into a plot - especially a blockbuster mainstream movie - will make it easier to "implant" the ideology into the audience's heads...and thereby by making it "mainstream" as well; by giving it a positive spin, embedded as some kind of positive turn of events, that leads to a good outcome of the plot.

If you overdo it, you usually alienate the general public. That's like "trying too hard" in advertising.
