Colin Trevorrow, the director of the Jurassic Park, has taken to Twitter to respond to some fan's criticism of the first trailer for the dinosaur movie. The first full-length trailer for the new film was released on Tuesday to near universal acclaim, though some hardcore fans of the original film had some picky issues.

One fan complained that the "gate" to the Jurassic World was "ugly" and less realistic then it should have been. Tweeting to Trevorrow, the fan said: "will the JW gate in the movie be CGI or practical? Everything was so seamless in the original."

"...the gate will be practical. Real wood, concrete and steel," the director replied.

"The gate is practical, the environment isn't. That shot was made specifically for the trailer. The film will be different," he added, to another fan.
