Lucky Star is a moe comedy. It frequently parodies its own genre and other anime and has a refreshing, off-beat humor and appealing characters with excellent seiyuu. It's tongue-in-cheek humor is often clever and sometimes sentimental. It's like a delicious cream puff. I'm guessing OP does not like cream puffs or other sweets, like ice cream.

There are some parts that might be too sweet, where it exudes so much superficial fan-service that we grow weary of its hollowness, but the show finds clever ways of recycling this excess into self-parody, much in the same way as Haruhi did. Ultimately it is a very self-consciously hollow production, almost superflat in that effect, and all the stronger for it.
