My beef with Syphon filter

Oh my gosh, syphon filter logans shadow had me so flaming mad. I thought I was going to toss my psp into a wall. I hated syphon filter dark mirror's story but at least the multiplayer saved that game. What a piece of disgusting garbage logans shadow is, the story is awful the ending after the credits made me want to gag. Basically, I felt like syphon filter as a series was great until the third game came out for psx then it all went downhill. Omega strain is just odd, not playing as the main character Gabe Logan was just lame. Dark mirror's story of Gabe having a kid was stupid since that was the whole point of the game which could've been presented as a file or side story. Logans shadow, handling of Lian's story feels slapped together to make her married. I feel like Dark mirror and logans shadow were only made to explain two characters backgrounds when this should've been done in the first two original syphon filter games. Yeah, I'm pissed off at Sony too. Not sure if I really want to buy MGS4 or a ps3.
