It didn't blow me away, but fun. Definitely worthwhile as a used game.
Pros:
Gotta love the ability to grab stuff, and the environment is very interactive.
Force powers are fun to use.
It's a fun frolic through different worlds, slashing and smashing your way around.
You can replay levels and collect stuff you didn't catch the first time around, and explore a little more.
Cons:
I hate grabbing stuff I don't want to grab. The targeting system was messed up a little too often.
Sometimes, the objectives were a little unclear.
We visit two planets twice, and in both cases, the second visit is tedious.
The quicktime events for killing bosses and big stuff were sometimes optional, sometimes not. I hate QTEs.
Difficulty seemed very uneven. On higher difficulties, some stages are just punishing. Also, running around and slowly draining a rancor's health can be very frustrating.
Not a fast enough reaction time. Sometimes you get knocked down, and you don't get a chance to catch your breath before you're tossed around like a rag doll. It's not the player; it's the game.
The story was good, but I'm not sure why they had to deviate from the basic Star Wars history to have the character make the light/dark side decision. It seemed unnecessary.
Using the different combos seems confusing. I can use a few, but I don't need to learn that much to defeat most of the enemies. I wouldn't have minded being able to pick up Darth Vader at the end, but I couldn't.
Some of the immunity to your attacks for different enemies seemed a little silly, but it worked out.
Overall, I'm glad I didn't buy it new. I spent $15, and it was worth it.
