That's a bit strange.
One review says they put in 25 hours to complete everything. The other says 60...
over double the time is a pretty big variance to be influence by gameplay style alone. You can only run so fast through a game... so who's lying?
Also, while some parts of those reviews bum me out (short, lack of interesting environments later on, buggy) some things like no (weapon spoiler)
and having that loot combiner/generator sound awesome. Finally, useless loot might actually have a purpose.
edit: On the flip side, this is the first time I've legitimately been excited in a videogame in years. It feels good to have that desire back. It's going to be hard waiting 2 months to play this but hopefully they get the bugs sorted out by then.
