Question: How was Blackfish rated by Metacritic?
About the article "Blackfish (film)", section "Critical reception".

Candidate passages:
Blackfish is a 2013 documentary directed by Gabriela Cowperthwaite.
The film premiered at the 2013 Sundance Film Festival on January 19, 2013, and was picked up by Magnolia Pictures and CNN Films for wider release.
"Blackfish" focuses on Tilikum, an orca held by SeaWorld, and the controversy over captive killer whales. 
The game receive favorable reviews from critics, garnering an 81% on review aggregation site Metacritic.
The game was rated as one of the top 10 independent video games of 2011 by VentureBeat's Jacob Siegal. 
"Pocket Trains" has been received well by critics.
Toucharcade rated it 4.5 out of 5 stars, saying it was "yet another fun title" when comparing it to "Pocket Planes".
Gamezebo also rated it 4.5/5 stating it was a "charming, highly addictive" game.
Metacritic described it as a "fun ride", giving it 76/100. 
 "Death Ray" "Filmstar" was a British magazine devoted to films.
Launched on 28 May 2009, "Filmstar" was the second magazine launched by Blackfish Publishing.
It was published monthly and aimed at movie-goers aged 25 and over.
"Filmstar" ended in October 2009 with issue 5.  
Endemic to south-eastern Australia, river blackfish like many Murray-Darling native fishes have managed to cross the Great Dividing Range via natural river capture events and so are found in south-flowing coastal rivers and streams in the eastern half of Victoria.
These fish are now often referred to as southern river blackfish.
This population shows a far great maximum size of 60 cm or more and about 5.5 kg.
Specimens this large were likely to be very old — 30 years or more — and are rarely seen now.
Logic suggests that due to these dramatic size differences, as well as isolation from the parent Murray-Darling species, genetic drift and natural selection, southern river blackfish are separate species.
The taxonomy has not been reflected to update this.
River blackfish continue the trend present in Murray-Darling native fish of speciating into primarily lowland species and upland species, with the upland species being in this case the two-spined blackfish, "Gadopsis bispinosus".
The two-spined blackfish is a more specialised upland inhabitant, and is found in the strongly flowing, cobble-bottomed sub-alpine rivers and streams of northeast Victoria, southeast New South Wales, and the Australian Capital Territory.
Though with the blackfish species perhaps you would say the split is lowland/midland and upland as there are overlaps in their range, and river blackfish are found in many upland habitats.
There are also indications that river blackfish populations in the southern and northern halves of the Murray-Darling river system may represent two distinct species or sub-species, with genetic and other differences.
The similarities between the "Gadopsis" blackfish and the "Maccullochella" cods (such as the Murray cod, "Maccullochella peelii") are striking.
There are some grounds for believing that Blackfish may be in effect a smaller version of Murray cod, inhabiting similar niches to Murray cod but in habitats that are too small for Murray cod (having said this, their distributions originally overlapped substantially), and there are grounds for believing that blackfish and Murray cod have drawn heavily on common genes at the family level.
FishBase, for instance, has scrapped the family Gadopsidae and listed the blackfishes as members of the temperate perch family, Percichthyidae.
A mitochondrial DNA study has confirmed a relationship between the Blackfish and the Percichthyidae but the exact relationship was not resolved in that study (Jerry "et al.
", 2001).
Further study is needed to resolve the relationship between the blackfish and the Percichthyidae.
Blackfish have a recruitment method similar to Murray cod, but with more specialisation to upland habitats.
Blackfish spawn in spring and lay a very limited number of large, adhesive eggs (<1000) on sunken timber (snags), or in the case of two-spined blackfish on submerged rocks.
Similar to Murray cod, the male guards the eggs until they hatch.
Upon hatching the larval blackfish are, uniquely, attached to their ruptured egg case by a tether until the yolk sac is largely used and the larvae are ready to commence exogenous feeding.
(This unique structure is presumably an adaptation to upland river/stream habitats, to prevent larvae being swept away in currents.)
