It's valuable on some level for this reason alone, and I'd argue all of Universal's parks would benefit from more "B" ticket attractions like this. The issue here (beyond the much-discussed gameplay and graphics performance problems), in my opinion, is that this attraction takes up far more space than it's worth. It's also arguably in too prominent a position for what it is, leading to misplaced expectations and subsequent disappointment.
If it was a tucked away "third" attraction in Minion Land? I bet the reception would be very different, but it's positioned like a minor headliner on the level of Minion Mayhem.
