Beyond bad in Portal 2.
Let me start by saying that Portal 2 is not the game Portal 1 was. Portal 1 was excellent, short, and straight-to-the-point. The second game is great, but not as the first. The first major flaw in it is this stupid robot Wheatley. I understand that they wanted to make a stupid robot's character, but they could've done it in more and better ways than this. This character is literally stupid in every way that I dispised its designer and spcifically its voice actor. The voice acting is horrendous... It is too damn loud, and this stupid character just pops up when in exact perfect moments of the game and ruins the experience for the player.
The developers could've played with this Stephen Merchant's voice just like they did with GLaDOS' instead of making it a real human voice; But they were actually more stupid than the character they were trying to make.
I wholeheartedly hate this Wheatley character. Check out the other characters: GLaDOS, Cave Johnson, and Caroline - and you might understand how this Wheatley character is the only odd bad thing in the game.
And of couse not to mention that Portal 2 for PC and PS3 is a port of the X360 version... and that is the second and last thing that I hate about this game.
