I'm fine with you holding that opinion. From it, I would guess that you played the Mass Effect games on an Xbox 360. I personally can't stand trying to play a shooter with thumbsticks, and I played the Mass Effect series on PC, using my mouse and keyboard.
I found Mass Effect 1's combat, storytelling, RPG elements, exploration, and explanations of in-universe lore superior to that of Mass Effect 2. I enjoyed driving the Mako, I preferred the cover system that allowed you to move in and out of cover seamlessly and wherever you wanted, rather than the one that only allows you to take cover behind pre-scripted chest-high walls or doorways (and required a specific button press to move into or out of cover). The second installment, however, contained better-written dialogue and more memorable characters.
