Faced with certain death, the cadets manage to find themselves cornered by a Elite. Caught by fear and a lack of weaponry they appear doomed until the Big Green Guy turns up to save the day with a cliched take-down-the-enemy-from-behind move to introduce the character. Cheesey, but it worked for a fine introduction of the Chief.
From there, our now armed and motivated cadets are escorted by the Chief to a Warthog so as to make an extraction point with a Pelican. Our heroes are besieged by a crew of Jackals who are raining green lasers and pink crystal shards from a roof top.
The camera work is fast and furious with a technique of showing a lot of action in slow motion which then lapses in to real time. A shot of the Chief jumping from a fair height and completing a land that would have put him into Olympic medal contention was very well done.
As I watched, I wistfully rued once more that I was watching 'Halo movie light' and not the full Hollywood production that Peter Jackson had planned.
I appreciated what appeared to be a nod to the infamous power of the original Halo: Combat Evolved pistol - the Chief managed to take down 2 or 3 Jackals with single shots from a fair distance.
Not sure where part 5 is going to take us, the simple plot story line suggests nothing major in terms of Halo canon will occur but maybe we'll get to see the next episode from the point of view of the Arbiter..... ;)
