Okay, I was lucky enough to see an early showing of the film two weeks ago, so I hope to see it again this weekend. But having said that, I have to say...LOVED IT. Still, I thought that there were pacing problems early on, and I would have preferred a more traditional version of the SHAZAM origin story (less "Big" influence). In fact, the movie could have easily started out with Billy already having his powers, as he continues his searches for his long-lost sister Mary (a brief flashback moment would have Billy meet the Wizard, who chooses Billy because, in spite of his rough exterior, was a person who is "pure of heart", a prerequisite needed to resist the temptation of the Seven Deadly Sins). Then again, having Billy already having his powers would take away the comedic aspects of him learning how to use those powers.
Nevertheless, I highly recommend this film for the general audience, though it might be too racy or scary for young kids. Good job, WB! Keep it up!
