I bought this set, and I must say it's one of the best sets I've bought in the last few years! I'm going to review the set in 4 categories: Minifigs, Vehicle(s), The Funhouse, and Playability.
Minifigs:
1. Batman: A very cool minifigure. I like the blue and gray from the old comics and the 60s show. His cape is very stylized, and there's a lot of detail on him, including his Utility Belt and six-pack.
2. Robin: Again, very cool minifigure. He seems more tougher in black and red than in his usual "rainbow" of green, red, and yellow. His scared face is perfect for when he's hanging upside-down over a vat of acid.
3. The Joker: Better looking than the first incarnation! He looks really sinister and crazed. I prefer the new hair than the old "Vampire" one. His purple suit has a lot of detail, including the squirt flower.
4. The Riddler: Again, better than the first. I really like the bowler hat, and the crowbar works really well as his "?" cane. His torso shows a six-pack, although he was never buff in the comics, as far as I know.
5. Harley Quinn: Once again, better than the first. Her outfit really works, with the whole red and black pattern. I do wish she had a weapon, though. It would've been cool if she had her big hammer.
Vehicles:
1. Batcycle: Kind of cool, but prefer the Batcave's Batcycle better.
2. Harley's Cart: Cute, moves really well on the track.
The Funhouse: Really cool. It makes up for what the old Batman theme lacked: a hideout for the villains. I love all the traps, which are: the giant hammer, moving floor, and trap door. The Riddler's little stand (maybe like one of those question-answering things), is cute too. The crane works really good, too.
Playability: Lots of playability, made up of the crane, the cart and track, the trap door, the opening Joker door, the Batcycle, the moving floor, and the giant hammer.
Minifigs: 10/10
