I think that part of why people don't like the paid story DLC is because of how expensive they are, and for less content. From Ashes (which was clearly cut from the game to sell day one) was $10 USD for about the same amount of content as The Price of Revenge and Kasumi's Stolen Memory, which were free and $7 USD respectively.
Leviathan went for $10 USD, where as Operation Overlord went for $7 USD. Again, they were about the same amount of content, but ME3s DLC went for more.
The real kicker is Lair of the Shadow Broker, which went for $10 USD. Omega, which was compared to LotSB content and length wise by the BioWare team frequently, cost $15 USD, was shorter than LotSB, offered less content, took up more storage space, and was buggy.
In total, the ME2 DLCs I mentioned add up to:
9 Missions
2 Squadmates (1 temporary)
4 Locations
2 Weapons
10 Upgrades
9 Achievements
Cost - $24 USD
Whereas the ME3 DLCs total:
16 Missions
1 Squadmate (2 temporary)
13 Locations
5 Weapons
10 Upgrades
9 Achievements
Cost - $35 USD
However, of these, 4 of the added locations don't actually feature anything relating to the DLC while another one is a base in Omega that no one counted as 'a new location' (all the mentioned ME2 DLC each have all their new locations counted as one apiece), one of the missions is 'go to Bryson's lab' which then leads right into another mission after the cutscene of the 'go to the lab' mission (there's another 3 missions that involve going to the lab), and 4 of the weapons were pre-order/new game purchase bonuses, thus changing our totals to:
15 Missions
1 Squadmate (2 temporary)
8 Locations
1 Weapon
10 Upgrades
9 Achievements
Cost - $35 USD
While according to BioWare's twisted logic you're getting a bit more, in reality, you're not. The ME3 DLCs take up more storage space and more from your wallet, yes, but other than that, you're not getting more.
