I don't have a problem mate (and honestly, I'm not really *excited* at all) I just question the assumption on which your complaint was based. As you say, this is a discussion forum, so if you have a problem with your opinions being challenged: deal with it.
You shouldn't expect to get a feel for the action/narrative balance of an rpg from a demo. All you should get is a feel for the tone, style and some hands-on with the core gameplay mechanics. Would it have been fair to base you entire opinion of ME2 from the Lazarus Station mission? No. That'd be crazy. Likewise, this is just the prologue. As for the later mission, you'd have to be blind and slightly concussed not to see they intentionally cut out any reference to the larger story and context.
