Alright, in my previous post, I made no effort to explain what I was saying, but I rather reposted my previous rant.
In my opinion, saying that ME2's story was poor compared to ME1's is wrong based on this:
The formula used in ME1's plot was reused in ME2. You don't see it? Well, let's see.
-Find some squaddies
-Do some story-based missions
-Kill the bad guy
Let's take a closer look at each step.
In my opinion, there is no point to comparing the recruitment stage between the two games. There simply is no comparison. Apart from the fact that loyalty missions are missing from the first game, the recruitment missions are much more interesting, and instead of recruiting (almost) your whole squad on the Citadel, you had to travel to various places around the galaxy.
I can't compare the story-based missions, since that would be completely subjective, but I mainly prefer ME1's missions. It should be noted, however, that ME2 had more story-based missions than ME1 had, so saying that ME2 wasn't as story-based as it should, is wrong.
The 'Kill the bad guy' part? Honestly, I did find the Battle of the Citadel impressive, but the actual mission that you were part of was far from impressive. Find Saren, talk to him, (fight him), Saren is revived, kill him again. On the other hand, the suicide mission was easily my favourite part of ME2. It depended heavily on your choices, and the story/action had an excellent pacing.
