I love the new sets and themes. Not because I never owned the old stuff either... My first sets were things like Black Falcon's Fortress, Black Seas Barracuda, Forbidden Island, and other stuff from the 80s. Every year stuff gets better and better! I love the detailed heads, new bricks, etc. Peach figures are awesome! Ya, that's right, I said it... peaches fucking rule and your yellow dweebs DROOOOL!
My least favorite sets are those stupid "box o' bricks" where they have some retarded looking brick built horse and a female torso + head + left over city construction worker orange legs that don't match at all but they had to get rid of them because they prolly have a quadrillion of them in their inventory. These sets are supposedly more creative... yet they are very limiting. I really don't care for what I can build out of 200 2x4 bricks.
The new sets have so much more interesting stuff and details. Take Black Falcon's Fortress for example compared to say the new Vampire Castle. Sure, BFF is a good sized building, it swings open so you can play inside, and that's about it.... there's NOTHING going on inside. It's devoid of any details or anything interesting. I saw the Vampire Castle all put together at the Lego store... blew my freak'n mind with it's awesomeness! There is sooooo much going on in like ever square inch. The design of the sets are clearly superior. All the new bits, props, weapons, food, etc. etc. add so much more to play with.
