I regret to agree - was very excited about this part because I found the first two parts of sensational - Infinite is rather disappointing. This special atmosphere that is created in the first part does not come on. I found that the 2nd part of many of the "weaknesses" of the first has well implemented. But in Infinite they have very many elements taken out, they were really fine in the 2nd part. I find the story not particularly stringent, and the various opponents Spoiler come to my mind so only at certain points in the game, and then no longer appear.
Who does not know the first two parts, and so far only Infinite played, that should make up. For those who found the first two games good - Buy Infinite likely anyway - but most do not expect too much.
