To IMAX not to IMAX, that appears to be the question with this movie. I have noticed a significantly higher rating from those that went to see it at IMAX. My working theory is that the increased audio/visual experience, combined with the unconscious need to justify the expense (not only money, but time and effort), results in a better experience. They seem to have missed the continuity errors and plot holes, do not seem to care about the crude characterizations, or bad directing of (some of) the human elements, or the 'diet version' of a story. Sure, we all knew it was to be rock 'em sock 'em Giants, but del Toro has been known to mix a little story into previous movies. For $200M and all the hype, I was expecting more. For all the advertising with Ron, I was also expecting more than 5 lousy minutes of campy acting due to the bad script (thanks Travis ?Clash of the Titans? Beacham).
Good SciFi? Not even close. A wormhole is a doorway. If monsters can come in, water can go out. Since all oceans are connected it would be a global catastrophe. Then there is a drift with a giant monster's brain that just did not die? That is like suddenly showing up at Microsoft's HQ and being asked to take over executing their PR department, when you have no PR experience or prep-time. Far too alien to make heads or tails out of it, yet somehow it works. The multiple levels of convenience in this one major plot device really shows the care that went into this script. Then there is the glaring discontinuity between high-tech robots and relatively low-tech everything else. Not as bad as Bad Robot turning a very high-tech starship into a flying low-tech refinery. That many pressurized pipes exposed to the vacuum of space would destroy the Enterprise with *one* hull breach. But surely someone had to point out the helicopters used in PR should have been upgraded visually to match the fact that they can apparently carry about 5X their normal capacity in perfect synchronization, without drifting.
7/10 for first viewing, 6.5 thereafter (pure CG movies degrade over time). Apparently IMAX is worth about +1.5 to +2.0, so if you are going to see it and there is an IMAX within a reasonable distance, I suggest making the effort (if the ticket price does not offend you too much, that is). If you do not see it in IMAX, then try to avoid the 3D versions. The glasses are well known to kill the color range of movies, and this is 85% CG, and the 3D is more of an afterthought than a selling feature (just like most 3D movies). Check this out for a more in-depth analysis of the poor 3D experience with PR. [http://www.cinemablend.com/new/3D-Or-3D-Buy-Right-Pacific-Rim-Ticket-38471.html]
Edit - ROFL, I just found out that Travis Beacham wrote the prequel comic to PR where he had the monsters killed with nukes, but in the movie says they were killed with conventional weapons. Way to go Travis! Your sith master, lord Lindelof must be very pleased (and getting ready to strike you down).
