I went to the Aquarium with no expectations as this was the first time I've been to one. Overall the experience was positive but I had a few issues:
1) It took less than an hour to go through the entire aquarium. I'm sure with kids that would double but for the cost there's I'd rather go to the ROM or AGO.
2) I don't know why they thought putting a soundtrack to the aquarium was a good idea. I guess it is a Ripley's venue (with animatronic Shark and everything)
3) It felt cheap. On day two of being open the "Shark Vision" already had a broken handle
Would I go back? No.
