Question: Why is the man's groin blurred out in the fight-scene at the Japanese sauna? It's an R-rated movie (or unrated, depending on the cut of the film you watch), so it's not like they couldn't have shown it. The best I can figure is that it's a reference to the fact that genitals are blurred out in Japanese media due to "decency" laws. Is that what the joke was?
Question: How is it that Thomas can understand what the rabbits are saying as shown in the make-up scene and no other human can?
Answer: It's not clear if he actually can hear them or not. It's implied in the film that it's possibly stress or a mental break that is causing him to hallucinate their voices, or is suddenly thinking on a brain wave length that can understand them. If it's the former, it's coincidence that he hears similar to what Peter is actually saying. Either case explains why he suddenly can hear them when nobody else can around them despite them talking in front of people.
Answer: The humans can actually understand the rabbits. Because notice during the scene when Peter is about to put the carrot in the Old Mr. McGregor's pants, the rabbits are talking quietly, most likely so Mr. McGregor doesn't hear them. And then there aren't any other scenes where they talk at a normal volume, or talk at all around humans, except for at the end when Peter is apologizing to the young Mr. McGregor.
Question: How did Pooh know the guy he met in the park was Christopher Robin?
Answer: Since Christopher Robin is his only human friend, Pooh naturally assumed it was him. True friends always find each other no matter how much time has passed.
Question: I don't understand one thing: who really kidnapped Brooks? The real ones or the kidnappers set up by Gary? If the real ones kidnapped Brooks, how did Gary's fake one get Brooks? How do Gary's fake actors intersect with real criminals?
Answer: Brooks was kidnapped by Gary's fake kidnappers. Everything to do with his kidnapping was set up by Gary. Gary did it to make people realise he'd be fun at their game night. However, Brooks was in league with the actual criminals and assumed they were responsible, which is where the mix-up happens. Eventually, the real criminals show up in the third act. Basically, it's two separate storylines that converge at the end through a comedy of errors.
Question: Maybe I'm foolish but if they're poor then how does Kate afford a nice looking car?
Answer: Just because someone is low income doesn't mean they can't own a decent car. Kate could spend what little money she has to pay for her car and still consider herself poor because she has no money left over after paying bills. Plenty of low income people still own decent cars because they are more reliable and require less maintenance than an older car, and are thus a good investment. Kate has three children, works two jobs, and goes to school. She has to have a good car to get back and forth and there's no way she could afford a major repair on an older car, so buying a new car is actually a smart choice for her situation.

I'm not sure what this comment is a response to, but it's not an answer to this question.
