I'm not 100% sure about "bought off" but a few, usually respectable and trustworthy reviewers published somewhat odd reviews. The inflated scores struck me as favors to friends at Respawn rather than straight up payola.
Especially if you look at reviewers private accounts. I mean, if you give a game a 5/5 or 10/10, shouldn't you be playing it at least once a week? Most haven't touched the game in months but they tend to play games they scored lower a lot more. At least it helped me filter out fakes from genuine reviewers, a list that's unfortunately getting shorter with time.
When TF first came out, I was flamed for saying that Respawn and it's products won't be that much different than Activision. They haven't done much to prove me wrong and Respawn just pulled off another typical Activision move:

The TF thread here died a while ago and that's the best indication about the game one could need but if one missed the beta and is really itching to try it, $36 is better than wasting $60.
