I finished Bioshock 2 yesterday and I found myself really disappointed. The game itself is pretty good, but my complaints are mainly directed towards the ending of the game. First of all, the game hypes up that you need tons of ADAM and all to get stronger, but at the end of the game I felt like I didn't really need much of it. I simply had to hold back enemies and destroy pipes. After the Fontaine boss battle in the original Bioshock, you would think that they could've done better here. Alas, the least they have you doing is killing the same group of enemies you killed earlier and shoot pipes. Then end cutscene didn't make it any better (I went for the good end) where it was pretty much "Yeah everyone made it out and they all lived happily ever after." 
 
Is anyone else disappoint? I am very disappoint.

Well you died in the end, which made me a little sad.
 
I still prefer this ending to Bioshock's.

It was much more fun gameplay wise then the first bioshock, but the story was pretty stupid. As far as the final fight goes the Fontaine boss battle was stupid and easy, all you had to do spam everything you had at him, the fight with the two big sisters was harder then that. 

Subject Delta dies in the end? o_o 
 
I didn't really know that, I don't think. The last 30 minutes of the game were like whaa.......

From Wikipedia: 
 

There are several possible endings depending on how the player has performed during the game; these are based on whether the player has rescued all the Little Sisters or harvested ADAM from them, and if they have spared the lives of certain non-player characters (like Holloway and Poole) within the game. In general, if the player's actions are benevolent, Eleanor will save Lamb, and if otherwise hostile, will allow Lamb to drown. When the pod reaches the surface, Eleanor and the rescued Little Sisters find a dying Delta barely hanging onto the pod. Again, depending on the player's actions during the game, the ending will change. If the player has generally performed good deeds, Eleanor will absorb ADAM from Delta, taking her father's spirit into herself, and leaving Rapture behind forever. If the player has performed too many destructive actions, Eleanor will absorb Delta's power and use it to make herself even stronger to dominate the world. A mix of actions may leave Eleanor to opt against absorbing Delta's ADAM and mourns for Delta's passing.

He died because of the bond broken between Eleanor and Delta, when she was so put close to death from suffocation. And I can only say as much for the Good ending, but Delta dies so he can then, somehow, become apart of Eleanor...or something. It's pretty screwy nearing the end. "

I had no problems with the ending.

I got the good ending and it all made perfect sense to me after listening to all the dialogue throughout the game. I loved the ending, it made me feel good.
