This is a bad film, action and effects are very good. The dialogue and plot are both extremely POOR!

Rating: 4/10 (10 June 2009)

The plot is so poorly thought out it is untrue. Suspending disbelief is one thing, but ignoring all plausibility is another matter.
The main plot of Marcus is pretty lame, but it would be acceptable if it was well played out. All the little things in the film are wrong, amazingly a super intelligent wargames AI is unable to triangulate a radio signal, the dialogue between characters is extremely limited, there is no character development and it gives no indication of any emotional connection with each other, the humans are using technology solutions against a vastly superior technological force, Skynet exhibits an emotional response about a small pointless video screen being destroyed...Again I could still extend my suspension of disbelief past all the little problems if the major elements were OK.
Unfortunately everything about this screams poor writing. The plot is wafer thin and yet the director saw fit to have Skynet explain the plot of the film just before the finale! If you need the villain to explain the plot then you haven't done a good enough job writing the plot in the first place!
Skynet, the ultimate strategy computer, decided that 2 terminators is adequate defence against hundreds of humans?? Skynet is also unable to muster any reinforcements when the aforementioned amazing plan of 2 terminators vs 100+ humans starts to fail.
The "trap" Skynet lays is pathetically obvious that I would be surprised if a 3 year old fell for, and even if you did fall for it why would your submarine be blasting out a signal when Skynet appears to be completely inaccessible from the water? I cant imagine that the leaders of the resistance have the cognitive capacity to actually run a submarine!
Again Hollywood fails with its car chase...amazingly the chase scene is even less plausible than Wanted's Dodge Viper vs Delivery van....this time it is super agile motor bikes verses a pickup truck! For some reason it takes ages for these bikes to catch the pickup truck...even relatively slow bikes can hit 60mph in 6 seconds...a relatively sprightly winch laden pickup truck could maybe be looking at 15 seconds...the pickup truck is even travelling in a straight line and hitting obstacles.
And then there's the fight scenes...Terminator 1 and 2 made sense, when Arnie attacked to get some clothes what did he do...he punch straight through the guys stomach... in Terminator 4 for some reason he decides WWE wrestling is the best form of attack. If a super strong robot attacks he will either try to punch clean through the character or crush him, I was waiting for the Terminator to clothesline John Connor it was that silly!
They really should have looked at the script and had a complete re- write!
Basically I have given 4 stars because the robots are cool, explosions are cool but lets face it if it wasn't a terminator film it would be straight to DVD...
