Lesser Sylvester and Tweety is not all bad though, not all people like the series but I personally do get enjoyment from them. Granny has next to nothing to do other than sing the title song and while Tweety is better and has a decent balance of cute and anarchic he is too much of a plot device and doesn't have much that is funny. The animation is not bad and is better than most animation nowadays but for Looney Tunes while colourful and fluid in places, others are a little scrappy and lacking in vibrancy.
The music is typically terrific, it's beautifully orchestrated and rhythmically lively like a vast majority of Looney Tunes cartoons. It also synchronises very well with what's happening with the animation, especially with Sylvester's rowing. The title song is very catchy. The humour is mostly in the visual gags rather than the dialogue, which is not bad either but there's much fresher and wittier elsewhere. The gags are very funny, hilarious even with Sylvester bagging all the best moments. Especially good were with the crab, seagull and Sylvester's two attempts at jumping off the bridge(his scream in the smokestack gag is priceless). It's not everyday where you see Sylvester water skiing either. The anchor destroying the boat gag was a little predictable but still funny. The cartoon is fast-paced and is not too repetitive. Sylvester is great fun here as always and he's easy to root for. Mel Blanc's voice acting while with not very much is characteristically reliable.
All in all, there are better Sylvester and Tweety cartoons but Tugboat Granny is entertaining enough. 7/10 Bethany Cox
