1) The acting was good! In-fact really good! Elizabeth Olsen did her best and was legitimate scary in her portrayal of a witch.
NOTE: If you think it was all about Wanda and not enough about Strange, it is because Wanda was the villain of this movie, but she is portrayed as a superhero before. So, the paradigm shift didn't took place that easy.
2) The story is pretty-twisted and I believe there was not a need of that. Some parts just feel like extremely lazy writing, like the scene with Christine and Strange in Sinister Strang's Sanctum.
3) Marvel these days, especially considering NWH and MoM, is relying way too much on CGI and special Effects. But they were really good. Could've toned it down a notch.
4) Cinematography, Set design and overall scene setups were amazing and Sam Raimi's unique touch was clearly visible.
5) There is a pinch of Horror that could've been nudged up a lot, was a bit dissapointed, especially after 2019's announcement event where the movie was promoted as MCU's first "Horror" Superhero movie.
6) If you went to watch Cameos, you were doomed to be dissapointed. I went tonwatch Dr. Strange, Magic, Witchcraft and the capabilities of Scarlett Witch and I can't say I was dissapointed at all. Wanda's powers in this one are just about right, considering Strange is extremely Powerful too.
