Lockers (both the requirements to use them and the cramped, hot spaces they occupy, continue to be one of the most common complaints at Universal guest services so I'd be sad if this ride opens with the same circle of hell scenario that Forbidden Journey still has.
If Universal's legal team insists on remaining stricter and more paranoid about being sued than every theme park operator on the planet (including Disney which is no small feat) they have got to find a way to make the process seamless. The relocation of the Mummy lockers to the Paradise Theater and the removal of the fingerprint scans were steps in the right direction but then they went ahead and shrunk down the free lockers to the size of a postage stamp which was kind of one step forward, two steps back. And then of course there is the absolute hilarious hypocrisy of requiring lockers on a ride like Men in Black in the name of safety while at the same time having thrilling and highly turbulent water rides that would effectively ruin your belongings if brought on-board with "optional" lockers that you have to pay for. I'd argue backpacks placed in the bottom of a log on Dudley is far more "unsafe" than some of the other rides that require lockers.
Meanwhile at Disney you can hop on Rock N' Rollercoaster, Dinosaur, Space Mountain, and Tower of Terror with an army backpack, shopping bags, a pet carrier, a beach umbrella, and an antique bedroom credenza and cast members will just say, "please place everything on the floor at your feet."
