Most people were dismissive of BTR because they didn't think that they were a real boyband, nor that they could really sing, they thought that the guys were just actors and that they were just playing characters. They weren't really taken seriously, nor were they promoted all that well, and weren't able to really take risks. The fact that all three of their albums made it onto the Billboard 200 chart, in the top 20 no less, when they (to the general public) weren't seen as a big group so to speak, was pretty impressive. They all had great comedic timing and really worked well together. Also, their show was legit funny, watching the seasons on Netflix and I'm falling out like I ain't watch these episodes back when they first aired. They all have very distinctive/different voices (I can always tell who is singing what line).

Yes, their dancing wasn't the best, (not all synchronized and smooth like K-pop bands nowadays) but like I've said in my billions of posts if you can hit that acapella, work/sing like an actual vocal group, and harmonize together than that is all that I care about. Big Time Rush is a VERY underrated, unappreciated, underestimated vocal group.
