Lego Star Wars brings 2 great franchises together, and works nicely.
The good thing about this is that the gameplay runs smoothly, and the way they done some of the more advanced characters (like the droidikas) are quite good. The multiplayer is entertaining, but after 3 hours straight doing the same thing, you get bored of get quite quickly.
The bad thing about this is that the camera angle can get in the way when you don't want it to, and might make you kill yourself. Luckily, it's addictive enough to keep playing.
Overall Lego Star Wars is a great game, but can eventually get old, just like Cookies and Warm Milk (milky wilky).
