Based on the very positive reviews it received in the standard guide books, we were eager to check out the Adler Planetarium. We wished we hadn't. We were stunned by how amateurish and dull its offerings were, particularly given Adler's high ticket prices. The technical quality of the exhibits is poor and they impart little new or interesting information to either children or adults (e.g., the exhibits include two pup tents, one air conditioned, and the other heated, to demonstrate the difference between hot and cold...It wasn't clear to us who needed this demonstration to understand the difference). The "3D" movie of the Milky Way galaxy sounded intriguing, but its execution was embarrassing. It was not 3D (it was a messy, 2-color blur, and everyone in the audience was in constant motion, trying out different points in the small room to see if they could find a "sweet spot" that would yield the promised 3D experience), and it shared no more than the scant information that was presented tediously in 5 or 6 other exhibits in the Adler. The guide books rave about the 30 minute movies presented in the pseudo-planetarium "StarRider Theater," and we assumed that seeing one of these movies ("Black Holes") would make up for the disappointments we'd experienced touring the other exhibits. No such luck. There's not much technical wizardry to be seen here, the information shared can be fit on two 3 x 5 note cards (and was presented in 5 other Adler exhibits), and it was a fairly soporific experience (we weren't the only ones in the audience who were trying not to fall asleep...and judging from some nearby snores, not everyone was as successful as we were). Avoid the Adler, and spend your time and money at the vastly superior and far more engaging Field Museum.
