I'm now 100% convinced most of the overly bad reviews are from people that didn't watch the movie.

Rating: 9/10 (7 March 2019)

Disclaimer: I'm not putting a spoiler tag because I don't give out story points but I do mention moments, tones, acting and reactions so please thread lightly if you want to go with a clean slate wich I recommend.
So just came out of the movie (it came out the sixth here) and I can say this is not a female agenda movie! I'm a male and I loved every bit of it. There's a couple of scenes that reminds us this is a girl granted but these are very subtle or used for somewhat comedic effects, but for the most part male/female is interchangable. She could be a man and the story would be basically the same, so it's a non issue. ( I make this point because of all the controversy, but rest assured it's all bull)
This is a troubled hero trying to find what it all means and Brie Larson plays it very well with subtle tones, a crescendo of roguish attitudes and humor that reflect her inner turmoil. The trailers don't make it justice at all. Samuel l. Jackson is at its best minus the profanity and the deaging thing is mind blowing to say the least. The banter between them flows so well. The supporting cast are scene stealers all of them. Maria, Monica, Talos, Coulson, Jude law, Annette and the freaking cat. The action scenes are riveting, well put together and the finale! In the words of doctor Bruce banner, you guys are so screwed now! The beginning gave me a heartache (you'll see) and the first endcredit scene got cheers from the public. The story is one of the best in any shm, I was glued to the seat for 2 hours and change but it flew by. And it's funny, more than I expected, with that MCU signature humor. Again the trailers don't make it justice.
Now, I gave this an 8/8.5 ( have to watch it again if I'm keeping the 9 or downgrade it to an 8) rounded to 9, but it's a 8.5 because it tries a little too hard to include scenes tying to the larger MCU where it didn't need them. The movie stands on it's own merits and it would be slightly better without the "see what we did here wink wink" moments.
Overall it goes to my top ten easily and one of the best most unique origin stories in the mcu. Highly recommend to see it. I plan to see it at least one more time as I mentioned.
