Sorry to bump a fairly old thread, but I think that the prequels and The Hobbit are very different in terms of quality. For one thing, the acting in The Hobbit was fantastic, particularly Martin Freeman as Bilbo, who I think is perfect casting. The acting in the prequels, well, you can’t even call it that, it seems as if George Lucas told them to be as wooden as possible with dialogue, only letting them act when they aren’t even speaking. The CGI in The Hobbit is also pretty good, albeit a little cartoony, but far better than the visuals in AOTC and ROTS (I actually feel that the effects in TPM mostly hold up, for the time). The characters are also very fun, especially in An Unexpected Journey, which is by far my favourite of the three. The action scenes are pretty great as well, apart from anything involving Legolas. All in all, while I don’t really like Desolation of Smaug or Battle of the Five Armies, they are far better than even Phantom Menace (which I feel is a good, not great film, trapped inside a mediocre one) and if I were to rate all of them, it would go like this:
An Unexpected Journey: 3.5/4
The Desolation of Smaug: 2.5/4
The Battle of the Five Armies: 2.5/4
And the prequels:
The Phantom Menace: 2/4
Attack of the Clones: 1.5/4
Revenge of the Sith: 1.5/4
The prequels, by the way, were not the worst films ever made.
