Will I be let down by Resistance 2?

[Barozi]

Resistance 2 is a very good game with an awesome campaign.
I always hear people saying RFOM has a better campaign, but they never say why.....

R2 campaign:
+ Huge boss fights
+ great visuals (colors FTW !!!)
+ location variety

- no co-op campaign

+/- 2-weapon-system
