45 Mins I will never get back

I have always enjoyed IMAX movies for their content and the fact I am watching a 6 story tall screen with an amazing sound system...but sadly those amzing factors did nothing for this movie... Since I had heard no reviews or previews or write ups...I was under the assumption it was possibly a 3d documentary about some ghost hunters maybe...I was dead wrong obviously...Where does this movie go wrong? I figured every single way possible. The CGI was decent...reminded me of early CGI movie PC games like 7th Guest/11th Hour and Myst..Nothing Hollywood extraordinary here whatsoever. The live action actors merged in with CGI is the worst I've seen...low budget...low acting...Obviously I coul rant and rave but the bottom line here is don't waste the money...period
