I love IMAX movies.The dizzier the better.My wife, Jennifer, not so much.I remember being one of the “select” 50 or so to sit in the old mostly empty-seat IMAX theater at Cedar Point — now home to Valravn coaster — and have an air-conditioned window to the world of science.Heck, I even remember the crowded Circle-Vision 360 theater in Tomorrowland at Walt Disney World.And who could forget the tortuous inflatable doom theater along the Geauga Lake midway where you sweated away while watching an out-of-focus ride on a San Francisco street car or seeing the vantage point of riding on the back of a roaring fire truck.The creature comforts at the Cleveland Clinic Dome Theater are much, much nicer than any of these other venues ever were.The first two documentaries to grace the screen via the new three-projector, laser-illuminated projection system billed as the first of its kind in a giant cinema dome setting will be Journey to Space and Tiny Giants.Sure it’s great to learn about the next era of space exploration for NASA and the “astonishing lives” of some of the smallest animals.The real thrill is the theater will be showing some Hollywood classics on a giant domed ceiling thanks to the installation of a new Digital Cinema Initiatives (DCI) compliant xenon projector.That’s a fancy way of saying films for the masses like 1982’s Poltergeist can now be shown.The horror classic will kick off a classic movie series at 6 p.m.
