Deus Ex to Deus Ex : Invisible War - just took everything that won awards in the first and threw it away
I was also dissapointed with Thief 2 to Thief 3 - much as it made a great media centre, the Xbox fell out of favour for me for being party to the messing up of these two titles.
More recently I was disappointed with MW2 vs MW
To a lesser extent I didn't like the change from fun, retro Resistance 1 (with the Chimera pursuing plan A, let's freeze the planet) to improved graphics but not so retro Resistance 2 (with the Chimera no apparently apply plan B, let's romp about in the sun with an unspecified plan and forget all about freezing the planet)
Try to be reasonable... its easier than you think...
