Here's what's wrong with it in my opinion
This will probably contain spoilers and certainly contain strong opinions (because I love films)
But:
The CGI was crappy - too much studio green screen not remotely meshing with CGI backgrounds
The lighting was terrible - there were scenes on the open water where there were 2 direct light sources lighting each sides of some of the actors faces when there would have only been one - this just made it look stagey and fake and of course not mesh with the CGI backgrounds
The handling of the story was: this happened then this happened then this happened - there wasn't enough conflict where we don't know what happens next and are watching it played out in real time in front of us - I just felt that much more removed from their story - of course being told the story in flashback doesn't help either
The dialogue and characters at times were a bit clunky - do you really think after weeks with out getting a whale they'd get all melancholic when they finally catch one and it dies? They'd be screaming their heads off in glee. Or when they're on the island and Chase get's all philosophical with the Captain 'we are dust' etc -- way too clunky and premeditated from the writer
And who's story is it anyway? Chases? Pollards? Young Nickerson? Old Nickerson? There's even an element of it being Melville's. It was never really clear who's it was - if it was handled better it could have been all of them in concert except Melvilles ~ and the conflict and resolution could have been Chase and Pollard finally coming to an agreement and respect with Pollards statements at the enquiry
Of course there were plenty of things good with it:
The subject matter, and Howard's respect for it
What they were *trying* to do with the CGI - but the underwater CGI was very good as it was - the rest just sucked
I just can't believe they got a hundred million dollars for it - because the script lacks most of the elements that makes films popular - so why put $100M into this? - obviously because of Ron Howard's name - but if some unknowns had rocked up with this script I dare say the studios would have seen it in a clearer light.
None of this is to say it's a bad film just that the story and subject matter could have been dealt with in a better way, in my honest opinion - I look forward to hearing yours :-)
