"I have to confess that before seeing 'L5: First City In Space' I was an Imax Theatre virgin. Like most virgins, I harboured high expectations, particularly as I was going all the way the first time - - to a 3D production. Obviously I was leaving myself vulnerable to being disappointed ... but I wasn't. Although I can't draw direct comparisons with other Imax productions, my guess is that if you've previously patronised a 2D screening you'll find the 3D experience twice as compelling (notwithstanding the arithmetical anomaly). Computer generated imagery is in abundance, but even more riveting is the genuine NASA-supplied footage. The 3D perspective can be a touch surreal at times, but it never ceases to enthrall. There is an unexplained virtual travel sequence (basically Star Trek's 'holodeck') that invites scepticism - - a small leap of faith for the credulous, a giant leap of gullibility required of everyone else - - but generally the film provides a realistic and absorbing glimpse into mankind's imminent future. The only other flaw is a lame attempt at drama. No androids are predicted for next century but a few could have easily substituted for the cast - - it's not a demanding script. At 34 minutes duration, however, a dashing narrative is hardly a necessity. L5: First City in Space is still a highly entertaining cinematic experience. "
