Incredibly annoying and dull main character (especially after such an awesome protagonist in the first game), story that introduces a million plotlines but never bothers to resolve any (you're basically being fed half the story on purpose), crappy and clunky forced combat sequences, crappy and clunky forced stealth sequences, no puzzles whatsoever, instead you get to solve a crappy minigame on the main character's cellphone.
And last but not least, the biggest crime: April Ryan character assassination.
The game is only worth it if you loved TLJ and want to see some characters and locations from the first game again.
