Yeah - the sound was too loud in places. Shame because I thought the point of Imax was to make things more 'real' so getting the sound wrong kind of ruins it.
The plot was OK for an SF film for the beginning but when Ann Hathaway does the 'I think love might be a force in the universe' I almost threw up. Some of it seemed to be nicked from Arthur C Clarke - the end sequence owes something to 2001 and there is something from 'Rendezvous with Rama', and Arthur C Clarke novel.
Films are still overloading the effects and CGI atm but I guess they are playing with a new toy. Once they get it out of their system, hopefully we will get some better movies again.
