What the producers have used as a selling point for the movie (it took a 100 years to complete) has set it up to be ridiculed and sadly for legitimate reasons. I can forgive bad CGI but not poorly recorded dialogue, ever. It sounds terrible in some areas and almost average in others. The image is barely professional in parts too. It looks amateur mainly because it's so soft and cheap looking.
The story itself had me wondering why no one had taken this team to the side early on and questioned its overall message and goal. It has lots of genres blended together but with out a cohesive tie. I was lost for most of it and even laughed at some of the silly lines. I reasoned that if this had the intention of being a parody or spoof comedy it would be fitting.
It doesn't fail because of its low budget roots. It doesn't fail because of its funny CGI. It fails because it's a weak story constructed poorly and the producers let the sound down (cardinal sin). It fails because we expect more in this day and age and despite the 'time' this took to complete it just doesn't cut it.
