Personally I'd say no. I'm struggling to get to the end, but I won't be beaten by it.
I think the second one will have the niggles ironed out, but for me the first has lacked any cohesive story, has questionable mechanics, and the weapon pickups are tediously similar. On the upside, once you've leveled up popping someone's head off with a sniper is incredibly satisfying. Or the 2 shot caustic revolver also hits the spot.
Masochistically, the screaming gives me gaming wood.
