why is it a bad review?

yeah they are damn bad, from the looks of it, its highest score is going to be an 80-85 =/....o well, im still getting ACII for my ps3 though ^_^

I think considering this is a PSP version of a popular PS3 game, that prospective buyers should be aware of what they're getting in this game and what they're not getting when buying the PSP version. Now lets think back about what made LBP great in the first place; fun physics based platforming, creating and sharing levels, and...multiplayer.

Now I'm not going to judge whether a lack of any form of multiplayer should have negatively affected the score. I'll leave that up to the individual. However, for the amount of people that are already familiar with LBP, and for the amount of people that saw 4 player co-op as an important feature in the game, you'd think it would at least be mentioned in the review that there's no multiplayer. You know, somewhere. Just as a heads-up maybe. Just for those that would naturally expect the game to have it because the previous title does. There's not one sentence in that entire review acknowledging the existence of multiplayer ever having been in the series, and doesn't acknowledge the lack of it in this game.

This might just be for me but I feel that the user created content was the main pull of LBP not the multiplayer

Secondly, there's only one sentence in this review that acknowledges what I would think what be worth putting a little emphasis on. There is only one plane in this game instead of two. There's no background and foreground, just straight 2D platforming. The review passively mentions it in the paragraph about creating levels, and gives it a portion of a sentence, "there are two planes to the level instead of three this time around". That's it. If you blinked, you'd have missed it. You also have to decipher that by having only two planes to work with in the creation mode, that means there's only one plane to play on. 

There are 2 planes in the game.  If you watch the video you can see him jumping between the 2, he even comments that you still get a little stuck like in the PS3 version (1:19 in the video)

Third, every problem that is addressed, which is game crashes, levels that feel empty and slowdown when floating around in edit mode are shrugged away because it's a handheld game. I mean really? Other games don't get this sort of treatment. They have game crashing issues and typically get scored negatively because of them. The only issue that actually affected the end result is the empty levels.

I agree

IGN's PSP team is quickly becoming as bad as the old Dreamcast team they had. Everything is a 9.0 nowadays.
