We must agree to disagree. Ordinarily I like Chris Pine a lot, but I felt like he mistimed and forced his lines a lot in that film. Under normal circumstances he should come across as the better actor (than Gal) by a wide margin, but somehow he didn't in WW. All in all I felt he was quite a let down as Steve Trevor, who was a very watered down version of Pine's take on Captain Kirk. In contrast Gal came across as genuinely strong and compassionate which is what made her so likeable.
I have never suggested that Gal is a great, or even good actress, but for whatever reason she nailed the role in WW. I was one of her biggest naysayers going into WW, but came out stunned by how good she was. I wouldn't be surprised if the next non-WW project I see her in, she's awful.
As far as physiques go, after seeing Gal in FnF she put on quite a bit of muscle for WW, as naturally she's very thin. She has a height advantage on BL, as Gal is 5'10 to BL's 5'7". In the WW heel-boots Gal is probably about 6 foot.
We didn't see much of BL's physique as she wore a padded spacesuit for pretty much the whole film. TBH I don't worry about an actor's physique that much, even for superhero films. While actors like Hugh Jackman and the MCU Chris squad (Evans, Hemsworth and Pratt) have all put in the time to show off their chiselled torsos and biceps is that really necessary ? To me the performance is much more important, which is why Michael Keaton was a good Batman.
If BL had been better as CM I would have become invested regardless of whether she was rippling with muscle.
