This is an odd episode, not a bad kind of odd but it's also sorta good. You see, it's good because it's no longer predictable. Before if you've played HL1 you know exactly what will happen in the next episode..however now you have no clue what will happen. Although this isn't good because I feel knowing what will happen is part of the fun of watching Freeman's mind. The commentary, and reactions are great so it's what keeps people waiting to see the next episode. They know a alien or some vortigaunt will creep around the corner, and Ross will surely make some good comment on it. It's sorta like Romeo, and Juliet if you know what i'm getting at here. You get told that both Romeo & Juliet will die, but you don't get told when. Just like when you know a good scene will appear in Freeman's Mind, but you don't know how Freeman will react to it.
Anyways, good twist of events. I like it, and I'd love to see the Combine invasion go on while he is sleeping in the jeep. Something of the sort.
