To be entirely honest I think The Escapist should have provided a more balanced review of this one.
I say this because I notice that there is no mention of the simple fact that the game has become almost entirely linear. Yes, there are cinematics, and a lot of things have become a lot more user friendly, and the way they use the phasing is interesting. On the other hand previously exploration was both encouraged and nessicary. Right now as things are, you pretty much get lead from one group of quests to another, and there isn't exactly a lot of stuff out in the boonies, that encourages you to spend time exploring off the beaten paths to see what other quests and content are out there. Even what quests are in the mini-hubs tend to be sitting right there where they send you.
While it's been active for a bit before Cataclysm, it's also noteworthy that with the new talent system you wind up getting less points overall, and as the review put it, choosing a talent tree is like choosing a subclass. That's not nessicarly a good thing because it ruins a lot of the depth of the game, and you see a lot less people creating builds with skills from various trees. The game even changes your class name, based on what talent tree your using so your skills are easily identifyable. You know longer see say a "Death Knight" and have to guess what he can do based on what you might see him using (or what he tells you) you can examine him and your pretty much going to know what kinds of skills he has.
What's more all of those cinematics tend to ruin the immersion of the game for me. Typically I don't feel like I'm in control of much that is going on, and acting as a spectator, and sadly comedy relief, for other characters.
To put things into perspective, you see that submarine scene with the character looking out and go "oh man, that's cool". I suppose it is, but what your not seeing is a big part of the quest chain where you pretty much keep constantly being rescued by this super-Shaman. The climax of the quest chain even involves pretty much following him around through the final battle (single player) and watching him destroy elite mobs that attack you while your attacks more or less bounce off ineffectively until his animations go off. Granted this ends up with the abillity to enter an instance to finish business (for a group), but for a lot of this your pretty much wandering around playing gofer of the "gather these, kill those, click on this" variety down a linear path.
The comedy relief aspects come about because there are quests like "put this mind controlling squid on your head, so we can see what happens". Now, I don't know about you, but if some gnome told me to do this, I'd tell them to go frakk themselves since I already know what it does (having collected said mind controlling squids from the creatures they were controlling). Yet I can't progress the chain/storyline until I do something that blatently idiotic. Let's not get into a bit where you intentionally let a shark bite you and carry you around in his mouth as part of getting it to line up for a harpoon (I'm not kidding). Blizzard has performed the rare feet of making it so half the time I feel like I'm in someone else's adventure, and a lot of that time I can't even take my own character seriously. There was always a bit of silliness in these games, but they are taking it to a whole new level.
Don't get me wrong, I'm not saying that this is a bad expansion pack for the game, I am playing it despite not being fond of "The Avatar Crisis Rides Again" (old D&D referance) and thinking they should have retired Azeroth gracefully for the time being. I am saying that judged entirely on it's own merits all of those innovations have come at a cost.
I'd give this a more fair rating of three, or three and a half stars. Yes it has cinematics, but they aren't always GOOD cinematics (though they can be), it has ongoing storylines that are more overtly developed (you don't have to read as much for the story as well), but that comes at the cost of exploration, and much of an incentive to head off the beaten path.
I'm not knocking it, just trying to be fair, I'm sure some people will come to oppose what I'm saying on principle, but there are plenty of people playing who have been having the same thoughts.
