I rode Operation Enterprise about 2 weeks ago in Moviepark Germany. I had quiet a high expectation but i must say, It wasnt very smooth for a 'new' Mack ride.... It's definitely a backrow ride with the twisted spine being the best element of the ride. For me it didn't exceed expectations, but for the park a good addition. I still really like it tho, it was just not as good as i thought it would be.
