Not a (modern) Marvel fan, but always liked deadpool. For it's gruesome and fun scenes, 4th wall breaks and rebellious humor.
Marvel managed to "marvelize" Deadpool and it sucked. The plot was confusing and lack luster. It was very very redundant with jokes and with Deadpool fighting Logan every chance they got. Was immediately thrown off by the movie completely erasing the 2nd deadpool by cheaply using the "time portals". It used every poor marvel shtick such as; time loops, multi-universe BS, and needing to know the lore of all the characters and their movies.
This was not a deadpool movie, it was a cheap "modern marvel movie". It fell flat and boring, total waste of money.
