First season is definitely better than season 2, however s2 is not terrible itself.
S1 is def amazing. Great plot lines. Quite funny and also interesting. Great actors and actresses. Just an awesome season overall. Some of the scenes aren't logical, esp in s2, but its for entertainment so i put my accuracy and logic aside and enjoy the show.
The first half of s2might be a bit off but its still quite interesting and engaging. The second half is definitely more exciting. Some plot lines in s2 were a bit random, but i still liked the overall show. Would have loved to see where the last cliffhanger of s2 would take us in s3.
