!!MAJOR SPOILER ALERT!!
Wow, talk about being disappointed. I'm sorry you did not love the game as I did. I thought it was brilliant and it sucks that you found so much to hate about it.
First off, your gripes about the game are small. I watched a lot of development videos and get what some of the changes are about. I am glad the Mako went, it handled horribly, especially if you had to find all of those scattered minerals. The scanning is tedious though, and I think it will go with ME3. You cant blame them for experimenting.
Like some people have mentioned, the old inventory was cluttered and horrible to get through. What makes the new fewer weapons nice is that the 3 shotguns shoot differently, while in ME1 all shotguns worked the same, just better aim or damage.
Spelling I did not notice, because my game's written dialogue was turned off... Why would you want to read it when everything is spoken. If I want to read I'll fetch a book from my shelves. So, moaning that the text is spelled wrong when you could just be listening to it is really a minor problem.
Well, if you finish at 60, you start ME2 at level 5, which is alright. Besides, you are re-engineered, so that's probably why your powers work differently. A lot has changed in 2 years.
Bioware changed a lot of things to make the game faster. Combat action faster, and smoother, which is something you cant blame them for. While the story still had choices to impact it.
And I do not get what you hate about the story. The reapers created a human like reaper, because they model their forms from the races they process. Sovereign was probably constructed from a squid-like species. Fighting the half formed human reaper was epic IMO. There are still some dark patches left as to what exactly is going on, but that is cause ME2 is part of a trilogy. ME3 will/should have all the answers.
Shame on you for dissing the crew missions. They were a lot more than what you got from the ME1 crew. It built a lot of their individuality, and showed a great deal of diversity in your crew. IE, Mordin and Grunt is awesome. Plus, Garrus is my favorite, and I love his character even more now.
As for the suicide mission... It was called that because no one ever returned from beyond the Omega 4 Relay. Going through is suicide, but Shepard said he will do it and return, cause he is the MFH! He used his brains to succeed, by updating his ship, getting the best crew he could, plus gaining their utmost trust, and even obtaining collector tech to go through. Shepard is the ultimate leader and warrior the human race has, which is why Miranda said they needed him and if he fails humanity will most probably follow. That IS why he could survive the suicide mission. Please pay attention while playing... Besides, if you do the rest of the game half-assed, most of the crew will die, and even Shepard can die.
Lastly, no, Bioware is not lazy. Remember all the same level designs used and reused during ME1, I think only missions had original layouts. All of ME2's levels are unique, Tuchanka, Omega, the Collector ship, the flotilla, even the new Citadel, all of these levels were uniquely and brilliantly designed.
Yes, you have less points per level, but no more redundant little points to add 2% accuracy, or 2 second biotic duration. The powers still have punch and now feel more valuable to spend points in.
Each Loyalty mission feel unique and well crafted to focus on the psyche of said teammate. They really evoke something personal once you get to know them. Samara's Ardat-Yakshi child, Thane's reflection on dying, Garrus being betrayed, Tali's treason. If none of these made you feel anything for them, then you have a heart dead as stone.
Moreover, the graphics are truly breathtaking. Just the work put into the art are reason enough why Bioware are not lazy.
P.S. The reason Liara 'acted' cold is because she had to keep her cover. She did kiss you, but she did not act all that warm. She is being watched after all, and her goal is to stay strong in bringing the shadow broker down. During her conversation you do see the softer Liara emerge, though not for long.
