I personally have the almost the same feeling as original one expect:
1st is the fact that the main story is easier and better looking.
2nd visuals are looking better than previous one,but at cost of shadows...sad.
3rd it gives you almost all DLC(expect soundtrack)from previous game.
4th the voice acting is better,but development of characthers is non-existent still.
5th is story is somewhat remastered. For example on stage where you get the suit,you instead destroying the wreckage,you destroy drones instead.
6th the ending is MUCH easier than previous one. Previous game had it very hard.
So far my reactions is the same: mixed.
The game is of course better than previous one,but the feelness of underpower combined with bad controls makes it not good.
For 20$ like normal one its overpriced,but for 10$ or 5$ it may worth it. For over 10$? Unlikely.
