Had it all
This flash really had it all. Obviously as you've said the fights need extended. One other thing I think would only help would be if during the fights maybe you could make a blue flash every time chief gets hit (I know the level of difficulty flash this was so I'm not sure how easy that would be) Showing his shield going down. Not that not having it took anything away from an already maxed out vote, but it would be neat.
I'm not sure if you're making it a "series" or if you're just going to make more like you said about the terminator. You should incorporate both into it, sort've a "meanwhile" thing where as the terminator is looking for John Connor, Chief's still looking for the skull. That sorta thing.
Oh and lastly, the whole entire time that dang toad was there I was hoping and preying you'd do what you did. So bonus points for that.
