I think ME2 felt more like a tv series, given that it had a really episodic format to it.
As for Shepard's reincarnation, they did give him some extras with the Lazarus project. All those upgrades you can buy/research like hardened skin, muscle enhancements and bone structure alterations are for you cybernetic upgrades. Also, if you read the description of the Widow in ME2, they say that a normal human cannot handle the weapon. Shepard can only do it because of his augmentations.
... Lasers for eyes would of course have been cool though, very 80s. 
Yes, every store in the galaxy was waiting for the first human to be revived through cybernetics, then provide upgrades for him and him alone.
According to ME1 codex anyone can upgrades to their strength, as long as you dont add new abilities according to the Sudham-Wolcott Genetic Heritage Act. Which is probably why we don't get to add new abilities in ME1. I don't know what went on in ME2's story and lore department, but holy hell its a mess.
Unless you play a Renegade, then you get glowing eyes and scars. TIM seemed obsessed with not changing Shepard and keeps stating it, so he was a bit of a perfectionist and missed out on upgrading Shep to be more, unless you count the new biotic implant as something.
I found ME1 to be an action RPG. They had nice moments that gave it a movie-like feel, but ME2 definitely felt more like a movie imo. Then ME3 felt like mostly a movie we had no control over except for the action scenes. Bioware always goes for that movie-like feel, but I found between all 3 the balance was off. I will never tire of playing the games, but that imbalance will never change no matter what I do and I have learned to try and ignore it.
I hope ME:A will be an action RPG with more emphasis on the RPG, and movie like elements will be restricted like ME1/2.
