I'll agree that there wasn't much to be excited about from watching the trailer.
This was more of a fan service teaser as the demographics of the viewers are the already existing Halo fans. As a Halo fan I was excited to see the significant graphical improvements that they've made.
I'm sure that the marketing trailer/TV spot will be far more action oriented to entice newcomers.
Do people still honestly not know the difference between simply having an opinion and 'sticking the boot in'?
