The main point of "Heaven is for Real" is contained in its title, so you know where you're going with this one before you even buy the ticket. The film is based on the best-selling nonfiction book by Todd Burpo, a Nebraska pastor whose 4-year-old son, Colton, had a near-death experience during emergency surgery and came back talking about a green-eyed Jesus, laughing angels and all sorts of real-world stuff that there's no way he could have known about except if he saw it through some mystical experience (or was coached by his dad, as some cynics might think).
