Can you forgive 1 bad game in the game franchise?

[Simulacrum]

Res 6,Castlevania LOTS,every Mario game I have played (this gen,from Ds to Wii,expect Kart),FF XIII and many more (lately) .Because I hated these games, I no longer have any intrest in the game franchise.Sure I do check if game gets 10/10 of 100/100 and check if maybe, franchise has gone back to what it used to be.

But most of time I do forgive 1 or 2 bad games like FF XII,Dmc2,Resistance2,Res5,GTA IV etc...So I did forgive FFXII and RES5 because I have been huge fan since I was kid and I guess they were OK games and got their sequels but...Just horrible games..
