I loved FF8, but at the same time had some really serious beef with it - First and foremost the GF/battle system.
I might have "misapplied it", but seriously, the first time I played the game, every battle was either (1) A massive draw-fest for stocking up on magic, or (2) Spamming GFs while using boost to deal with HP heavy enemies - Which meant that every singel battle ever fought was a chore and extremely boring.
Also, limit break system was retarded. I went through most of the game without getting a limit break even once(the only games that did limit break right IMO was FF7 and FF10).
My second beef with it was the lack of impact your choices for Squalls dialogue made in terms of personalizing the character -
I mean, every time you had a nice comeback, and a rude comback, it didn't matter what you chose, because Squall would ultimately revert to "whatever... I was just kidding" or something to that effect, and nullify the choice I just made.
My third beef was have the plot ultimately got butchered over time - Going from awesome(to the ending of the first disk), to wtf(from the prison scene and onwards).
As mentioned, the memory loss + childhood friends thing, strange new enemies popping out from nowhere(Norg, every witch except Edea), and a few a bit too convenient plot devises(like the discovery of ragnarok).
Sometimes, I'm almost(just almost ok) convinced the guys who made the "Squall is actually in a coma"-theory were right, because it's so sketchy at times.
My fourth beef was that I didn't find the enemies imposing or scary. FF7 did a great job in presenting the bad guys, surrounding them with mystery and giving you the feeling that you didn't amount to shit in comparison. I remember actually being worried about catching up to Sephiroth after the Nibelheim flashback, because I knew he'd own my party and I'd have to start all over again, or something to that effect, because I hadn't levelled enough or missed out on some necessary materias etc.
Jenova was creepy as hell - The Shinra building scene was like taken out of Resident Evil.
Ultimately, witches with large breast relying solely on magic that I can counter with reflect, isn't very scary.
But FF8 had great graphics, great soundtrack, Laguna(which is arguably the must human of all FF characters), some real beautiful and creative locations - And overall good style - So it's still one of the best overall IMO.
My two favourite FFs are 7 and 10. I think there is just something about the pacing and presentation of those two that I think stands out in comparison to the rest of the series.
