IMAX. If you see this movie in a theater, don't be a scrub...spend the extras $5-$10/ticket and see it in IMAX. It's worth it.
That said, with this movie, we must welcome back the fun summer blockbuster! This movie wasn't a good movie, the plot was full of holes, the dialogue was corny at times and the story was obviously predictable...but you know what, I didn't care AT ALL, this movie freakin' ROCKED my face off (literally, with The Rock...lol!)
This is on the level of Armageddon...massive destruction, action sequences leveled on top of action sequences...but just all around entertaining! Decent humor, lovable characters...and California getting absolutely destroyed!
Is this a MUST see? Not at all...but if you do, see it in the biggest way you can. LOUD and HUGE in IMAX. I feel like I'm a spokesperson lol!
