It did for me, so in that sense I'd say it was a great advert.
A week after seeing "Brick" I was in Target and scooped up 3 new sets. I grabbed the ARC fighter, Droid Tri-Fighter, and Wookie attack playsets which, as of April 2nd, I had planned to wait until clearance or at least until I saw the new movie.
So like I asked, did Brick inspire you to go out and buy more goods ?
*to be fair, I should add that Target was running a sale so I saved a fistful of dollars but the enthusiasm was still there. Man, you have no idea how hard it was to pass on the sale-priced Clone Turbo Tank !
