Are Metro: Last Light and Metro: 2033 the same game, with updated graphics?

I'm thinking of buying Metro: Last Light, though from screenshots I have seen it looks the same as Metro 2033 simply with better graphics.

Are these two games basically the same or are there substantial differences between them?

No, Last Light is the sequel to 2033. There is a Metro 2033 Redux which features 2033 redone on Last Light's engine, as well as some other enhancements.
