I don't mind anything in Leon's campaign aside from the guy looking for his daughter in the beginning. I don't mind anything in Jake's aside from all the vehicle sections. I don't mind anything in Chris's campaign. I mind everything in Ada's campaign.
simmons sucks and yes fighting him in his 84 forms was no fun. especially in the second playthrough and onward it's just boring and tedious because you already know he keeps coming back no matter how much you shoot him.
when i raise teh difficulty for another playthrough , i plan ahead that i will need an hour for leon's first chapter ebcause you have to walk slowly untill you can walk out of campus ... i mean yeah we know the first play through must put us into the atmosphere but my god everytime ...? every friggin time ...? and its not like you'll face any zombies nooooooooooooooo you just need to find some teenager who eventually will bite her own father's head off and then get owned hard by you .... now that takes the fun out of a pumped up start
