I went back and played the original Portal once I heard that Portal 2 was coming out, and enjoyed Portal so much that I bought Portal 2 (once it had gone on sale on Steam).  I really enjoyed it, and like the stark feeling of the later levels, as well as the new "character".  It was certainly a worthy sucessor to Portal, though I realize the original Portal was short, and this game was quite a bit longer, I still get the impression it was a bit shorter that what I would consider standard (i.e. Half-Life 2).
 
There was enough new stuff added, making this game a fine successor to the original.
 
But I would have been happy even if they had just given me more test chambers for the original game.
