"The good - you get a cool looking helicopter, 3 new minifigs, a compartment that can drop snake bombs, flick fire missiles (if you like those things) and a price that is fairly decent for the number of parts, especially with newer styled pieces. I love the way they used castle headgear as part of the engines.
The bad - This thing is delicate! using the flick fire missile will probably end up causing you to knock off the armor plates they are attached to when you fire them. The front cockpit and other parts in that area easily come apart and even with instructions nearby, are difficult to get back together properly. Also, the back tail, and stabilizer (snake)fins have lots of extra movement, but that causes the fins to get jumbled and locked up. If they were going for a snake tail type of look then they should have made the tail end of the helicopter more stationary, or at least more stable. Poor engineering I think. No kind of landing gear or skid parts for the underside; missiles would look/work better there.
Overall - The new minifigs look great as does the helicopter. However, if you are giving this to a child on the younger end of the spectrum, I recommend against that. There are a handfull of rarer parts but most are neon green in color so not as much usage elsewhere. I got this mainly for the minifigs, but the playability seems a bit shoddy"
