Half Life 2 is extremely boring. The gameplay is bland, the guns are terrible, it's extremely linear for a game that wants to be more open, the AI was stupid and I just kept scratching my head wondering why the hell anyone would think Half Life 2 is the greatest game ever made. I played it years after it's release, so maybe it's because I didn't fall for the the huge amount of hype that it had at it's release. The only things that I actually liked about it was probably the presentation, a couple of the characters and the soundtrack. I usually have very low standards when it comes to shooters, but Half Life 2 has been given so much praise, that I felt that I had to raise my standards specifically for that game and they weren't met. I also didn't finish the game because it started to feel tedious.
Basically I disagree with the dev.
