Top critic status usually goes by publication, such as the more established newspapers. Anyway, Kyle Smith can be funny as long as you don't take him too seriously.
Nah, it's just Kyle Smith, that's his shtick, he gives negative reviews to almost everything and tries to be witty while doing so. He is a big fan of Frozen, though.
I am pretty sure it's a joke in reference to the Cinderella one. The teaser had been give a running time of 1.33.
The score is trailer music, similar to that from Frozen's first Japanese teaser.
How much has this film made in the UK? The site has it at 7 million but it doesn't seem to have been updated since the 10th of February.
Anyway, looks like the film is almost assured of breaking 450 million which is good. Was rather pessimistic about the OS grosses at first.
