I find Emily Deschanel's character much more annoying than when the show dbuted. Lately she seems to be bending backwards to be as irritating as possible. I know Eric Millegan and Jonathan Adams are long gone but sometimes I wish they could bring their characters back at least every now and then.
When they replaced Dr. Goodman with Dr. Saroyan, in my opinion, they made a major mistake. I like Ms. Taylor but her character is dry and really doesn't bring anything to the show. Replacing Zack Addy with Dr. Sweets was a bit sad, but in the beginning John Francis Daley (Dr. Sweets) was fun to watch, he isn't as much fun anymore, it's a shame, his character at least brought a laugh to the show at one time.
I actually like how Angela Montenegro grew in the show. I like Michaela Conlin's character much more now. As for Dr. Hodgins, he's still great, not much change, still likeable and fun to watch. The same can be said for David Boreanaz's character, he's enjoyable to watch and not much changed, except he seems to have forgotten he has a son, which bothers me a bit.
I still watch the show, but I don't look forward to it as I did in the past.
