hwat?
no. I honestly don't think so. At least Shepard talks in a way that is somewhat normal and expected from a person to speak like. In Heavy Rain, the bad acting is amplified by the unnaturally sounding writing.
The reason people are upset is exactly because Mass Effect was better than most of the games you listed and 3 seems to suggest a bigger drop in quality than 2 was, even.
As i said, personal preference... I can´t help but love detective stories, and there are so few of them translated into game format.

Regarding the rest of the game listed, i heartily disagree that any game in the mass effect series reaches the quality of writing.
Doesn´t mean i dislike the writing in ME1 and 2, it´s scifi opera and that is by it´s own definition as cheesy and heroic as it comes.

There's no BioWare masterplan behind Mass Effect 3 not supporting gamepads on PC - the team was overstretched and couldn't spare the time and effort required.
Edit: Bioware on gamepad support:
I call bullshit... what a piss poor excuse.
