Half Life has always been about bringing a compelling narrative to video games. There was a general suspicion that there was no way Half Life 2 would be able to follow in the original Half Life's footsteps. However, Half Life 2 not only did that, but it trumped it to a great extent.
Of course, the competition has had a lot more chance to catch now since when Half Life 2 was released, six years ago, so if you're not impressed compared to current day offerings than I'm hardly surprised.
Maybe if you're a really good observer you could notice that Half Life 2 next to a current day game fits right in and realize that this means HL2 was greatly ahead of its time.
