I've seen all 3 TAR Canada seasons and they're all brilliant
The casts are so diverse too. I won't go into spoilers but the only downside is at times it can feel quite predictable/repetitive. It really is good though!
And it's cool that Jemmett are on Season 4! I don't really care for them as much as everyone else does but I will probably root for them anyway!
If anyone cares btw I'd say 2 > 1 > 3
