I love this game! I have The Handsome Collection which is the most current version now but there are still some technical issues.
Pros
Most engaging and unique vault hunters in the series
Memorable side characters and bosses even if some get little time to shine.
Adds a lot of interesting insight to why some things happen and exist in bl2 and beyond
Great random vault hunter banter about the objectives or even towards each other
Unique to the series laser weapons, mobility, and this game introduced ice element
More Athena :) bester girl than even Gaige
Pretty fitting and fun futuristic music
Cons
Getting shot through walls, floors, and cover in general is the main one for me
Farming bosses feels lackluster and unrewarding
The grinder feels gimmicky, too expensive, and underdeveloped where it could've easily been awesome. It's still ok with exploits.
Non dedicated legendaries considered "world drops only" basically never drop ex: The Maggie
Getting stopped by small, sometimes invisible, pieces of geometry in or out of vehicles (not nearly as bad as BLGOTY though)
Color palette and environments are not very diverse, despite looking interesting
Not enough fast travel stations, leaving things feeling very backtrack-ey
Too much Pickle
Not much in the way of good story DLC
Verdict: Solid entry and I loved almost every minute! I think it only got so much negativity because BL2 was so outstanding
