I have mixed feelings. The game's riddled with questionable design choices that damage the core game mechanics, which I enjoy. The constant vehicle/weapon nerfing (especially with choppers), suppression blurring, the obnoxious desaturation when hit, flashlights practically blinding your character in daylight, etc., all seem like little things, but add up over time.
Also, the majority of the original maps are terrible; I have no clue what DICE was attempting with some of them. Thankfully, the DLC has largely been great, though I'm hesitant to say they "redeem" it when you have to pay extra for them.
And finally, the return of 64 player maps was welcome but also frustrating, because many of them weren't really well-suited for such a high player count. You have to figure out yourself which ones work better than others.
I think I enjoyed BC2 a lot more when I really think about it.
