If you find yourself coming to IMDb for a sneak peek at your next movie outing, please remember this rule: reviewers who vote a film 8* or more, if they have only one, or two at the most, reviews posted .. are probably what the industry calls "sponsored reviewers" or, in layman's terms, "professional bullsh**ers".
Unfortunately Father of Invention is one of those titles that the parent studio feels needs sponsored reviews, as you can see for yourself if you browse the few reviews here on IMDb (just click on the Author's name in the review); the film isn't terrible, but apart from Kevin Spacey doing his best, there really isn't much of a story to keep it afloat.
Rober "Bob" Axel has just come out of jail for marketing a faulty product (whait, what? do corporation chairmen go to jail for that? this film must be set in a parallel universe where criminal charges apply differently than real-life US), and he has to start again from the bottom rung of society, trying to rebuild all he lost, including his family, car, friends, and all that upper-crust stuff. He fails.
That's about it for a pretty mediocre film, with a very diminutive script, truly awful supporting characters, middle of the road acting, and lacklustre direction; Spacey is good, but the constraints of a unimaginative ..everything .. leave him no space to shine.
Avoid this film if you can, there are too many boring and inconsequential filler scenes in it to make this an easy sit-through, even with friends. Instead, do go see something else out this week, like Soldier Spy, Machinegun Preacher, 50/50, 1911, Heavy Times, or the superb Drive. Anything really, but not this. Or Melancholia.
Final vote, 4/10. Pretty bad.
