Ive been a public speaker before and often have to do presentations etc in my line of work..
You can always tell when someone giving a speech or presentation doesnt actually beleive what they are saying themselves!.. they look nervous and stiff.. they try to force a relaxed body language which turns out to be strange body movments which dont look natural.
Its not like this guy has done this review live (which might explain why he looks and sounds so nervous) but still, to me, he looks and sounds like he knows what he is saying isnt completly truthfull.
Notice at the very end how he tilts his head like as if he is trying to read something to the side... lol..
A sure sign that what he 'thinks' and what he 'says' are two different things
I feel sorry for him actually, Im fairly certain that he didnt write that script himself.. or if he did he was being influenced by someone.
And thats my opinion
