Also I think quanitifying the over-all reception is a tricky thing, and I wont claim what I said was right. There is simply no way for an 100% accurate representation. I considered RT, but that uses a dual scoring thing, a yes or a no, and that makes it difficult to gauge a critical response overall. Therefore I used metacritic that divides it into good, mixed and bad reviews. BvS had around 10 good ones, 10 bad ones, and 30 mixed ones. Hence I concluded BvS had a mixed reception. However I do understand all these evaluations whether that be RT or Metacritic have their own flaws, which I do know about. So there's that. I just meant that statement in an overall way, and I think its merits and demerits can be argued either way until it just becomes about semantics, and I dont think thats worth it.
I've never said that BvS is the worst movie ever or the worst review movie ever.
However, using Metacritic, there are other CBM released over the past 10 years that are worse:
Fantastic Four (2015) Score of 27: 1 Positive, 18 Mixed, 21 Negative
Green Lantern (2011) Score of 39: 5 Positive, 19 Mixed, 15 Negative
Suicide Squad (2016) Score of 40: 11 Positive, 26 Mixed, 16 Negative
Wolverine Origins (2009) Score of 40: 9 Positive, 19 Mixed, 11 Negative
Batman v. Superman (2016) Score of 44: 10 Positive, 30 Mixed, 10 Negative
And there are some that that were reviewed a little bit better.
X-Men: Apocalypse (2016) Score of 52: 16 Positive, 29 Mixed, 3 Negative
The Amazing Spider-Man 2 (2014) Score of 53: 19 Positive, 26 Mixed, 4 Negative
Thor: Dark World (2013) Score of 54: 22 Positive, 19 Mixed, 3 Negative
For me, this is just a simple eye or smell test. If Dark World is arguably considered the worst of the MCU, TASM2 the worst of the Spider-Man series, and Apocalypse one of the low end of the X-Men series, it's easier for me to see that at least critically, it's not really mixed since it seems more comparable to Wolverine Origins in terms of scores.
