You're absolutely right. Deep Space is more fun and with pleasant surprises.
Interesting read- Deep space was launched shortly after the theme park launch with a Bollywood celebrity, Varun Dhawan opening the ride open. However when people started visiting Imagica and started seeing the 'huge' rollercoaster right at the entrance of the park being installed and tested, the hype was created before its launch automatically.
Also Interestingly, Nitro was launched 6 months post the park launch with Imagica's first TV campaign going on air. Campaign theme- "Are you Man enough?" Umm, well!
