Here's where I stand on this.
Not a massive fan of any of the DCEU movies, but Wonder Woman was probably the best of the bunch. WW84 however is below average for most of the running time, and the last hour or so is really quite poor.
Firstly it's very inconsistent with Batman Vs Superman. She's basically introduced in that movie as having laid low since WW1, yet in this she seemingly speaks to the whole World via TV/Radio? And it's not like they used some reset button either. Everyone will remember that weird day in 84 when they were granted wishes and had to then recind them.
The wishes thing was pretty bad actually. Though not because it was too "out there", after all isn't that exactly what the infinity gauntlet ultimately does in the MCU?
More the way it was used was bad. We're supposed to believe that everyone in the World recinded their wish? Including people with terminal cancer? complete ********* in general? Nah. What about 84 Bruce Wayne? Didn't he ask for his parents back?
One of the poorest sections is Wonder Woman getting her arse kicked, killing Steve off-screen then deciding she can fly, after a seemingly infinity-length lasso grabs the airplane. All this just so that she can go home, change into her new outfit which has been built up as being near indestructible (rather than her sword), only for that armour to break almost instantly when she gets in to a fight with whatever it is that Barbara becomes.
She seems to have renounced using the Sword? Doesn't kill anyone etc?
And wouldn't flight have been quite useful in BvS or The Justice League?
And can a jet fighter plane fly from Washington to Egypt without refuelling? Seems unlikely.
Kirsten wiig is a good actress in general, but seemed a bit miscast here IMO. She looks pretty good for 47 as that 80's workout outfit didn't leave much to the imagination, but her character didn't strike me as being that threatening. She basically had Diana's strength at first, and I understand that Wonder Woman's powers had faded due to her own wish, but she had many years of training in combat/athletics and Barbara had zero.
