Better "shooters" than MW:
- Half Life 2
- Mafia 1/2
- F.E.A.R. (the AI behaves really amazing)
- MOH: Pacific Assault
- Metro 2033 (pretty short, but I really enjoyed playing it)

And there are probably many more laugh
About Modern Warfare: I liked the first Mission of the first part a lot (the ship thingy), but other than that it was just another well playable game (at least I played through it, in contrast to Far Cry and Crysis...).
