I watched DP 1 & DP 2 in the past day. This is definitely the most MCU feeling of the three films (not saying that at all because of cameos, it just felt a like while it was certainly a Hard R, it still played it a bit more in the vein of MCU formula compared to prior Deadpool films.
With that said, I really enjoyed it and it seemed like my midnight showing audience all were feeling pretty similar walking out. Cameos don't feel forced or without purpose like let's say, Multiverse of Madness. They worked much closer to the cameos in No Way home in that they just felt natural as they all had a connective tissue. It was a very nice sendoff to the Fox era of Marvel.
The movie probably could've stood to have had it's runtime tightened a bit, but I still thought it was fine. I wasn't expecting some masterpiece, I was expecting to have a great time at the movies and to laugh a good amount and the movie delivers on that where a movie like Thor 4, Quantumania and The Marvels for example failed miserably.
