I don't see anything powerful, flexible or impressive about Source.
Doesn't "compete" with Metro 2033? No game ever developed on Source qualifies as a dot on a line graphically compared to that game.
Physics? I'm looking forward to physics like this:

I don't really care if Source stays as it is, and Valve builds games on it.....a great game is a great game (I love Portal and HL).
What I don't understand is why this engine gets so much admiration considering how deprecated it is compared to other modern engines.
The "admiration" stems from how back in 2004 Source
was a nice jump in the industry, when at the time the only "competition" really was just CryEngine (the original, running the first Far Cry also back in 2004). Now in 2012 it's of course easy to say there's "better" engines, sure it's been eight years now, but back in 2004 CryEngine
2 did not exist and Unreal Engine 3 was still under development. To this very day one could argue that Source is still the most scalable and stable engine there is, and I myself would argue that it has the best
facial animation system when of course used properly such as in Half-Life 2 and Team Fortress 2, with only L.A. Noire's technique and technology for that purpose being better, but also being the only exception, but that's my opinion. I know facial animations can also be good in CryEngine 2 and UE3 (although I do prefer
body animations in CryEngine 2 and Frostbite 2, and also UE3).
And, keep in mind that back in 2004 the physics in Half-Life 2
were very impressive and probably became the unintentional Source's (or at least HL2's) mascot, it was on everyone's lips and articles. Does anyone remember I think was the E3 2003's G-Man speech demonstration that showed facial expressions and animations, along with the first in-game level demo of H-L 2's physics? I was personally quite blown away by that G-Man speech demo when I first saw it, I quite couldn't believe that it would make it in the actual game, but it did. I also recall that scene when in the demo of the level the player enters a building after being chased by fast Zombies outdoor (during night time), and once inside Combine soldiers try to force their way in, and the player pushes a washing machine against the door to demonstrate that physically the soldier wouldn't be able to enter the room due to the new physics system (but of course a lot in that scene was scripted).
Anyway, you really need to put yourself back in 2004's gaming context to understand where the admiration for Source comes and why it still has a clear legacy today.
