“For nostalgic fans of the ’80s or those just discovering Steven Spielberg’s classic sci-fi blockbuster for the first time, 21370 E.T. the Extra-Terrestrial represents an absolute must-have. The LEGO Ideas model is reasonably priced, features enough functionality and extras... More to justify its price of admission and successfully translates the look of one of cinema’s most ionic creations into a brick-built triumph.”

“The model has come a long way from the original E.T. THE EXTRA-TERRESTRIAL submission by Lafabrick, and I think the model designer has done an admirable job with the sculpting and how wrinkly and lanky ET looks. The LEGO ET model measures 24.5 cm (9.5 in.) tall, so scales... More very well next to LEGO’s other buildable characters. There’s a decent amount of articulation, and you can angle his head up, down and rotate it 360 degrees, as well as point his forefinger to symbolize E.T.’s desire to “phone home.””
